📝 About This Recipe
Sowans is a legendary, ancient Scottish dish crafted from the 'sids' or husks of oats, transformed through the magic of fermentation into a silky, tart, and incredibly nutritious cream. This probiotic-rich delicacy offers a unique flavor profile that sits somewhere between a fine yogurt and a delicate citrus porridge. Historically a staple of the Highland diet, it is prized for its digestive benefits and its versatile ability to be served as a comforting hot breakfast or a chilled, elegant dessert.
🥗 Ingredients
The Fermentation Base
- 4 cups Steel-cut oat husks or 'Sids' (unrefined oat bran or coarse oatmeal can be substituted)
- 2 quarts Filtered water (lukewarm, approximately 90°F)
- 1 teaspoon Sea salt (to help regulate the fermentation)
The Cooking Liquid
- 3 cups Sowan-suds (The fermented liquid) (carefully decanted from the fermented oats)
- 1/2 cup Whole milk or heavy cream (optional, for a richer texture)
- 1/2 cup Cold water (to adjust thickness during cooking)
Flavorings and Toppings
- 1 tablespoon Salted butter (high-quality grass-fed preferred)
- 2 tablespoons Wildflower honey (to balance the acidity)
- 1/2 cup Fresh blueberries (for garnish)
- 1/4 cup Toasted hazelnuts (roughly chopped)
- 1/2 teaspoon Ground cinnamon (optional)
👨🍳 Instructions
-
1
Place the oat husks (sids) or coarse oatmeal into a large, sterilized earthenware crock or glass jar. Ensure the container is large enough to allow for some expansion.
-
2
Pour the lukewarm filtered water over the oats and add the sea salt. Stir thoroughly with a wooden spoon until all the oats are submerged.
-
3
Cover the jar with a clean muslin cloth or cheesecloth secured with a rubber band. This allows the mixture to breathe while keeping out dust or fruit flies.
-
4
Place the jar in a warm, draft-free spot (around 65-70°F) and let it ferment for 3 to 5 days. Stir the mixture once every 24 hours.
-
5
Check for readiness: the mixture should smell pleasantly sour and slightly yeasty, and you will see small bubbles rising to the surface.
-
6
Once fermented, pour the entire contents through a fine-mesh sieve into a clean bowl. Use the back of a spoon to press as much liquid and starch as possible out of the husks.
-
7
Discard the spent husks. Allow the strained liquid (the 'suds') to sit undisturbed in the bowl for 2-3 hours. The thick, white starch (the 'sowans') will settle at the bottom.
-
8
Carefully pour off the clear liquid from the top (this is known as 'swats' and can be drunk as a refreshing tonic) until you are left with the thick, creamy sediment at the bottom.
-
9
Measure out 3 cups of the thick sowans. If you don't have enough, supplement with a little of the swats liquid.
-
10
Transfer the sowans to a heavy-bottomed saucepan over medium-low heat. Add the butter and a pinch of salt.
-
11
Whisk constantly as the mixture heats up. Like cornstarch or roux, it will thicken rapidly as it reaches a simmer. Do not let it boil vigorously or it may scorch.
-
12
If the mixture becomes too thick (it should be the consistency of a thick custard), whisk in the milk or a little cold water to reach your desired smoothness.
-
13
Cook for about 5-7 minutes on low heat, stirring continuously, until the 'raw' starch taste has vanished and the mixture is glossy and smooth.
-
14
Remove from heat and stir in the honey and cinnamon if using.
-
15
Pour into warm bowls and top with fresh blueberries and toasted hazelnuts for a beautiful contrast of textures.
💡 Chef's Tips
If you cannot find traditional oat husks, use the coarsest oat bran available to ensure enough starch is released during fermentation. Temperature is key; if your kitchen is cold, the fermentation might take up to a week, so look for the bubbles as your guide. Always use a wooden spoon for stirring fermented foods, as metal can sometimes react with the acidity and affect the flavor. To prevent a skin from forming on the cooked sowans, press a piece of parchment paper directly onto the surface if not serving immediately. Don't throw away the 'swats' (the clear liquid); it is highly probiotic and makes a great base for sourdough bread or a tangy beverage.
🍽️ Serving Suggestions
Serve hot in a bowl with a swirl of cold heavy cream and a sprinkle of brown sugar. Pair with a small glass of chilled 'swats' for a truly traditional Scottish digestive experience. Top with a dollop of rhubarb compote to complement the natural acidity of the fermented oats. For a savory twist, skip the honey and top with a poached egg and crispy bacon bits. Serve chilled in small glasses as a palate cleanser or a light, refreshing summer dessert.
