Digestive Biscuits.

Digestive biscuits
Here in the U.S. of A. “digestive biscuit” could evoke an image of something strange, indeed. First off, here a biscuit is a quick bread akin to a scone, and is frequently used to sop up dinner juices or served smothered in sausage gravy for breakfast (but not in my house). Growing up we often ate biscuits -- like these cheddar biscuits -- warm topped with butter.

Then the “digestive” part doesn’t sound too appetizing ...

But in the U.K. biscuits are cookies!
Biscuit comes from Medieval Latin, via a detour through France, meaning “twice cooked,” like biscotti. Whereas cookie, according to everyone’s favorite free online encyclopedia, comes from the dutch word koekje or koekie meaning “little cake.” You say biscuit, I say cookie ... let’s have a nice cup of tea and a sit down.

Digestive biscuits are like graham crackers -- light in texture, slightly grainy, and not-too-sweet. One of the ingredients is sodium bicarbonate -- baking soda to us plain folk -- and digestives were originally credited with having antacid properties, aiding the digestive process, and being good for people with “weak digestion.” Although one would think it’s all the nice whole wheat flour (or "wholemeal" according to U.K. ingredient lists) that’s good for the insides. Maybe they should have been called “digestible biscuits?”

I’m guessing the best-known digestive is made by McVitie’s, originally a Scottish biscuit maker, which started manufacturing digestives in 1892. They also make a chocolate coated digestive biscuit. I haven’t tried those yet, but apparently they are so popular that “... each year, 71 million packets of these are sold -- and each second 52 biscuits are consumed.” That’s one of the funnest statistics I’ve ever read! Fifty two biscuits per second.

I could easily consume numerous (although not 52) plain digestive biscuits in a single sitting with tea, milk, coffee, a mocha, or whatever is on hand. They go down easily, one ... after another ... after another ... after another ... They aren't available at our usual grocery store, but World Market carries McVitie's and Burton's (those are Burton's at the top of the post) and our local international grocer, Treasure Island carries them, too. A decent substitute is yummy Carr's Wheat Crackers, which seem like a grocery store standard.

Once smitten by store-bought digestives, naturally the next step was to find a recipe and make them myself. There is no shortage of digestive biscuit recipes, but which would be closest to McVitie’s?

First I tried this one from the King Arthur Flour company. They were delicious! And popular at home. But they were more like a light shortbread cookie and not crumbly enough so they missed the mark.

Take 1: A plateful of King Arthur Flour digestives. Light and sweet, but not quite the what I was aiming for.

Then I discovered the Great British Kitchen site, a wonderful place for recipes and other information about British food. Their recipe got me closer to the grainy, graham-cracker quality I like about McVitie’s.

Digestives are as easy to make as sugar cookies, with ingredients you'd likely have on hand. These required only one “special” ingredient: powdered milk. (SHUDDER.) When I was growing up we drank gallons of the stuff. I, for one, didn't enjoy it. However, it
was economical for a family of 12 and it was plentiful at the grocery store. Nowadays I don't imagine there's the same demand for powdered milk, so it’s hidden on the bottom shelf of the hot-chocolate-and-Coffee-Mate display. And it costs $9 a box! What would I do with four pounds of instant nonfat dry milk? Likely have post-traumatic powdered-skim-milk-drinking nightmares about it. How my brother grew to 6'3" after a sucking down that pale watery brew throughout his formative years is beyond me.

The recipe calls for just two tablespoons of powdered milk (I'd be manufacturing digestives for the rest of my life with that 4-pound box), so I substituted plain malted milk powder. I usually have plain and chocolate varieties on hand, for chocolate malted milk, pre-workout smoothies, and the occasional Chocolate Malted Milk Cake. As far as I’m concerned the plain flavor was the right substitute for powdered milk.

Take 2: Light, crisp, toasty, a little grainy, not-too-sweet ... perfect!

Next time I'll show you how I used my leftover King Arthur Flour digestives (the shortbready ones), along with the store bought kind, to make the now-famous no-bake
Chocolate Biscuit Cake requested by Prince William for the most recent royal wedding. Swoon. No, no, not for the prince ... for the cake of course!

Digestive Biscuits
From the Great British Kitchen
Serves: 36

300 Gram Plain wholemeal or whole wheat flour (10 oz)
4 Tablespoons Wheatgerm
1/4 teaspoon bicarbonate of soda (baking soda)
1/4 teaspoon salt
2 tablespoon skimmed milk powder
4 tablespoon sugar
125 grams butter (4-1/2 oz)
5 Tablespoons cold water
1 teaspoon vanilla extract

Combine the dry ingredients, then cut in the butter with a pastry blender or two knives until the mixture resembles breadcrumbs. Combine the water and vanilla and drizzle over the dry mixture. Blend until the dough can be packed together.

Roll out between two sheets of waxed paper until the dough is about 3 mm (1/8 inch) thick (yes, I measured it!).

Cut into circles or other shapes and bake on a greased baking sheet at 325 °F (170 °C, Gas 3) for 20 to 25 minutes. They should not be too brown. Cool on a wire rack and store in an airtight container.
