What’s in a name? Sometimes, quite a lot! Take biscuits, for example.

To an American a biscuit is a scone like pastry made with buttermilk and is often served alongside savory dishes like stews. In the South biscuits and gravy are served for breakfast. Just as popular, biscuits are also eaten much like scones with butter, honey or jam.

To a Brit, however, a biscuit is a slightly sweet crispy treat somewhere between a cookie and a cracker you would enjoy with a nice cup of tea or coffee.

So, now that we are all clear on the differences, these Digestive Biscuits are the British style and they have become our new favorite snack.

Used to be, back in the bad old days in the UK everybody stopped mid morning and again mid afternoon for a nice cuppa. Usually tea but sometimes coffee. It was said that a good cup of tea could solve all the world’s problems and it was true. For that 15 minutes while you sit back and relax with your cup of tea, all the world’s problems go away. Of course, they came crashing back again as soon as the tea break was over. But at least twice a day you could be assured of a little peace and serenity.

Typically you would have a little snack with your cuppa in the form of a biscuit. One of my favorites was (and still is) a McVitie’s chocolate covered digestive.

Digestive biscuits were invented in 1839 by two doctors in Edinburgh, the epicenter of medical science at the time. They believed (somewhat erroneously) that the biscuits aided digestion because they contained bicarbonate of soda, hence the name ‘Digestive”. There is no science to support this notion but to this day, McVitie’s digestives remain the most popular biscuits sold in the UK.

Here in the US making cookies at home is very common. Making biscuits at home in the UK, not so much, I think. It is so much easier to buy a packet of biscuits at the store. I am an avid food label reader and it distresses me when I read on some labels the preservatives and unpronounceable ‘stuff’ in the product I am expected to eat. There are some exceptions to the label reading rule, however, and McVitie’s is one of them. I mean, everybody is entitled to some guilty pleasures, right? And it’s not like I eat them every day or anything…

I can get McVitie’s where I live here in California but they are hugely expensive compared to UK supermarket prices and are usually at or near their ‘best by’ date. And so I always fancied having a go at making digestives at home. I’ve tried a few recipes and have been thoroughly underwhelmed with the results. Until a few months ago when I happened upon an article in the Guardian newspaper by their food writer, Felicity Cloake. In the article Ms Cloake compared recipes from a number of bakers and created her own, a composite of the ones she compared. I made them and they weren’t half bad. (You can read the original article here). I made some modifications though. So many in fact that even though I used Ms Cloake’s recipe as a starting point I feel comfortable claiming this one as my own.

I call for white whole wheat flour here. While not as ubiquitous as the red whole wheat flour, it is widely available in the US. Wholemeal flour in the UK is made from white wheat berries by default because that is the wheat most commonly used there. White wheat berries are not actually white, more of a tan color. The flour is less bitter than that made from red wheat and has a milder, sweeter taste.

The oatmeal I use is proper Scottish oatmeal (what we Scots would call porridge oats), not the Quaker rolled oats. Rolled oats are oat berries that have been steamed to soften them, then rolled flat, hence the name! I have ground up some rolled oats to use instead of the porridge oats to see how the biscuits would turn out. (I use a cheap – $20 – coffee grinder for this purpose as well as for grinding fresh spices but you could just as well whizz the rolled oats in a food processor). There was a noticeable difference in taste but it still made pretty good biscuits so, if you can’t find proper porridge oats, ground up rolled oats will do. Irish steel cut oats won’t work here. Again as the name suggests, steel cut oats are oat berries that are cut into large pieces rather than being ground like porridge oats.

I originally developed this recipe around a stick of butter. Here in the US, butter is commonly sold in 1 pound (450g) packages with each package containing 4 x 4 ounce ‘sticks’. How many biscuits you get out of this batch of dough depends on how big they are and how thick you roll the dough. I got 18 biscuits if I roll the dough 3/16″ (5mm) thick and use a 2-3/4″ (7cm) cookie cutter. I found that 3/16″ is a good thickness; any more and the biscuits don’t crisp up like they should and any less they tend to get too brown around the edges. However, 18 biscuits didn’t last long so I upped everything by 33% and now make 24 at a time.

So that raises a question; how do you get the dough to an even, consistent thickness? You can buy these rubber band thingies you fit over the ends of your rolling pin. The bands come in various thicknesses so you can roll out any dough evenly to whatever thickness is appropriate. You can also buy a set of plastic sticks at a baking supply shop. They too come in various thicknesses. You set a stick on either side of the dough and roll it out until the rolling pin gets to that level for even thickness every time. A clever idea, I thought. But me, being me, decided, “I can make these”, and so I did! Carpentry is one of my many hobbies I went to my workshop and fashioned a set of limit sticks out of some maple wood I happened to have left from a previous project. They work perfectly. I would encourage you to look for the commercially available product or, if you have the wherewithal, make some. It will make your baking life a lot easier, trust me!

Do you see those holes I poked in the biscuits? They are not just for show. The holes allow moisture to evaporate during baking so that the biscuits bake and crisp evenly. Otherwise the edges would crisp up while the center would not. Being mildly OCD about these things I poked 14 holes in each biscuit with a bamboo skewer for a total of 336 holes. That was getting a bit tedious so I made a spring loaded stamp to streamline the process. But again, that’s just me all over, isn’t it? A normal person would poke the biscuits a few times with the tines of a fork!!

You will notice that there is very little liquid in the dough; only 4 teaspoons. So, what binds the dough together? The sugar! The little bit of milk dissolves the sugar which becomes liquid. It does make the dough quite sticky though and that is why I roll it on wax paper and covered with a sheet of plastic wrap. Even so, the dough will still tend to stick to the wax paper, especially in warmer weather. I use a small off-set spatula like this one to lift them off the paper.

Now, what about chocolate? Chocolate covered McVitie’s digestives are a very special treat with either dark or milk chocolate. If you want to melt some chocolate and spread it on one side of your digestives, by all means, go ahead. Personally I think the biscuits work perfectly well on their own.

These biscuits keep very well in an airtight container for several days without loosing their crispness. Of course they don’t usually last that long!

Digestive Biscuits

A crisp, buttery and delicately sweet snack to enjoy with a cup of tea
Course Snack
Cuisine British
Prep Time 30 minutes
Cook Time 40 minutes
Time to chill biscuits 15 minutes
Total Time 1 hour 25 minutes
Servings 24 biscuits

Ingredients

  • 1 3/4 cups (9 1/2oz/255g) white wholewheat flour
  • 1/2 cup (3oz/85g) Scottish oatmeal *See note below
  • 10 1/2 TBS (5 1/4oz/150g) unsalted butter – cold from the fridge, cut into 1/2" (12mm) pieces
  • 5 TBS (2oz/55g) dark brown sugar – **See note below
  • 1/2 Tsp fine sea salt
  • 1/2 Tsp baking soda
  • 4 Tsp (20ml) milk

Instructions

Mix the dough:

  • Place the flour, oatmeal, sugar, salt and baking powder in a food processor and pulse several times until thoroughly combined.
  • Add the butter pieces and process thoroughly. It is important to process the butter into the flour until it starts to form clumps or the dough will be crumbly and difficult to work with. This may take up to 25, 1 second pulses. Stop and scrape down the the bowl a few times when the dough starts to climb up the sides.
  • Transfer the mixture to a bowl and add the milk. Toss gently with your fingertips to thoroughly distribute the milk throughout the dough. It should look like wet sand.

Prepare to roll out the dough:

  • Line two sheet pans with parchment paper.
  • This dough is very stiff and needs a sturdy rolling pin and some elbow grease to roll it out. Wipe your work surface with a damp cloth to moisten it. Place a piece of wax paper (greaseproof) about 18" (45cm) long on your work surface. (The damp surface stops the wax paper from sliding all over the place.)
  • Gather half the dough on to the wax paper and form it into a dense ball. Flatten the ball with the heel of your hand as much as you can. Cover with another sheet of wax paper or plastic wrap and roll it out to 3/16" (5mm) thickness. The dough may be a bit crumbly to begin with but it becomes more workable the more you roll it. With a 2-3/4" (7cm) cookie cutter cut out as many biscuits as you can. Transfer the biscuits to the prepared baking sheet using a small spatula. These biscuits don’t spread at all so you can place them quite close together.
  • Gather the scraps adding more dough from the bowl. Roll and cut more biscuits, transferring them to the baking sheet pan as you go. Keep rolling, cutting and gathering until all the dough is used up.
  • Transfer the sheet pans to the refrigerator.

Bake the biscuits:

  • While the biscuits are chilling in the fridge, preheat the oven to 350°F (175°C) with a convection fan. If your oven does not have a fan, heat it to 375ºF (190ºC).
  • Take one sheet pan out of the fridge and poke the biscuits 3-4 times with the tines of a fork. Bake for about 18 minutes on the middle rack, rotating the pan halfway through to ensure even baking. ***See note below.
  • Allow the biscuits to cool on the sheet pan for 10 minutes before transferring them to a cooling rack to cool completely.
  • Repeat with the second sheet pan.
  • The biscuits will keep for a week in an airtight container at room temperature.

Notes

* Scottish oatmeal is commonly available in the UK. Not so much in the US. Look for Bob’s Red Mill Scottish oatmeal where you live. Failing that, whizz regular rolled oats in the food processor until the are finely ground. The flavor won’t be quite the same as with porridge oats but still very good.
** Unlike flour and other dry ingredients, brown sugar is always packed into the measuring cup or spoon so be sure to pack it in when you measure it out. Unless you are weighing your ingredients of course – always the better choice in baking.
*** All ovens behave differently and have their own characteristics. In my oven it takes 18 minutes to bake a batch of these biscuits. Yours may bake a few minutes faster or may take a little longer. Trial and error will soon get you to the ideal time. Keep in mind, the biscuits will darken slightly as they cool so if they look a tad on the pale side at the end of baking, don’t worry, they will be perfect by the time they are cooled. 
If you are making these in the summer time in a warm kitchen the butter in the dough may start to melt. If it becomes too sticky to work with, place the bowl of dough in the fridge for 10 minutes to stiffen it a bit before continuing.

I am a self confessed foodie and food science geek (some might even say a food snob. I wouldn't disagree). I have been interested in food all my life but, circumstances being what they were, I began to practice my craft somewhat later in life. I love to pass on the knowledge I have gained over the years to anybody willing to learn. At the same time I am always open to learning new things, and not just about food...
