This vegan mascarpone cheese-style cream is made by straining soy yogurt overnight. Rich, creamy, and completely dairy-free, it's perfect for vegan tiramisu and other desserts.
Line the colander with two connected sheets of paper towel, leaving one sheet hanging over the edge.
Pour in the soy yogurt and fold the overhanging paper towel over the top to cover it.
400g / 14 oz unsweetened soy yogurt
Place a weight of about 650g (1.4 lb) on top.
If you're concerned about fridge odours, cover with plastic wrap before adding the weight.
Refrigerate for at least 8 hours. Ideally, continue straining until the yogurt reaches about 200–220g.
If you're in a hurry, you can add a little extra weight partway through straining, but too much may tear the paper towels.
Make the Mascarpone Cream
Transfer 150g of the strained yogurt to a bowl.
Use the remaining yogurt in other recipes, enjoy it as is, or add more to adjust the flavour if desired.
Add the shio koji, powdered sugar, and lemon juice. Mix well.
½ teaspoon shio koji, ½ teaspoon lemon juice, 2 tsps powdered sugar
Chill before serving to allow the flavours to meld.
Notes
The straining time and final texture will vary depending on the soy yogurt used.
I use Marusan unsweetened soy yogurt, made from soy milk only. In my experience, soy yogurts containing added sugar, starches, or other thickeners do not strain properly.
