Ingredients
- 3 eggs large, 180-190g weighed in shell
- 10 g egg white powder (U.S. option HERE)
- 10 g whey protein isolate (U.S. option HERE)
- ¼ tsp cream of tartar (U.S. option HERE)
- ⅛ tsp xanthan gum (U.S. option HERE)
- 20 g icing sweetener (U.S. option HERE)
- 1 pinch fine himalayan pink salt (U.S. option HERE)
- ½ tsp vanilla extract (U.S. option HERE)
Instructions
- smear a little cold butter over the bottom and sides of a baking tray (33cm x 23cm measured internally) and line it with non-stick baking paper.
- pre-heat oven to 160°C static.
- crack open your eggs, placing whites into a large mixing bowl, and yolks into a small one.3 eggs
- whip the whites with an electric whisk on high speed until frothy, then add icing/powdered sweetener, salt and cream of tartar, and continue to whip until you obtain a stiff meringue.20 g icing sweetener, 1 pinch fine himalayan pink salt, ¼ tsp cream of tartar
- without cleaning the whisk blades, whip the yolks with vanilla until they become pale and creamy.½ tsp vanilla extract
- weigh and mix remaining ingredients, tip them into the whipped yolks, and immediately whip to combine; the mixture will thicken quite quickly.10 g egg white powder, 10 g whey protein isolate, ⅛ tsp xanthan gum
- loosen this yolk mixture by whisking in 1/4 of the whipped whites, then pour it into the whipped whites bowl.
- combine manually using the detached balloon whisk, then scoop the fluffy batter into your baking tray (don’t worry if you see tiny specks), and spread it evenly edge to edge, squaring the corners.
- bake for 15 minutes.
- remove from oven and allow the sponge to cool for 5 minutes.
- flip it, and remove the paper gently (for a neater result, peel the paper by keeping it low and parallel to the sponge).
- rest the upside-down sponge over a rack for a couple of minutes, to allow any residual moisture to evaporate, then cut it as required for the dessert you intend to make.
Notes
Nutrition for the whole sponge: Kcal 320, NC 0g, P 41g, F 17g.
This sponge is slightly chewy and not a ‘cake’ intended to be eaten on its own. It is ideal if you want to provide bulk to a creamy dessert, and it’s best moistened with milk, coffee, etc.
The baking tray measurements don’t have to be exact. Obviously, a smaller one will create a taller sponge and a larger one will result in a thinner sponge.
