Step 1

Sift flours, yeast and 1 tsp salt into a bowl. Make a well in the centre.

Step 2

Place milk and creme fraiche in a small saucepan over low heat and warm gently until lukewarm. Add milk mixture to the well in the flour mixture, along with the egg yolk, then stir until a soft dough. Cover with plastic wrap and set aside in a warm place for 1 hour or until small bubbles appear on the surface.

Step 3

Whisk the eggwhite until soft peaks form, then gently fold into the batter.

Step 4

Heat a large non-stick frypan over medium-low heat and brush with a little butter. In batches, using 1/2-1 tbs batter for each blini, add batter to the frypan, then cook for 2 minutes or until small bubbles appear on the surface. Turn and cook for a further 1 minute or until golden.

Step 5

Transfer to a plate while you cook the remaining blinis, brushing the pan with more butter in between batches.

Step 6

Place blinis on a serving platter, then serve with a selection of toppings for guests to assemble their own.
