The BEST Healthy Biscotti Recipe: Sourdough Rusks (South African Beskuit) (2024)

Jump to Recipe Print Recipe

This healthy biscotti recipe is a spin on the South African beskuit (rusks) that we eat like a staple food. We dunk it into MANY coffee and tea’s we have each day, so it may as well benefit from the sourdough long fermentation so that we can easily eat the vitamins from the flour.

Healthy Biscotti

This recipe can be called “healthy biscotti” because it includes a long fermentation with a sourdough starter. If you are new to sourdough, read my post about why sourdough makes baking so healthy for you.

Sourdough starter is what makes this a healthy biscotti recipe, because the sourdough starter breaks open the minerals locked in flour and makes it better available to your body. When you pair this with good quality flour, you are actually eating nutritional food.

We don’t think of bread often as nutritional, but it can be when you use “real” flour and a sourdough starter.

South African Baking

Biscotti like this, South Africans call “rusks” or in Afrikaans “beskuit”. It is one of the most popular baked goods South Africans eat. We drink ample coffee and tea, and it is usually paired with at least one or two rusks. That is why it is very common for most South African housewives to have at least one rusk recipe in their recipe books and well practiced.

There are also many variations of this basic buttermilk recipe. Some add nuts, others oats. Other favourites are anise seeds or muesli rusks because of the “healthy additions”.

I’m pleased to let you know that you can have even the most basic buttermilk riks in a healthy manner – add sourdough! See description above it you missed why sourdough starter in baking is so healthy for you.
