• Combine both flours in a mixing bowl.
• In a separate small bowl, combine the melted butter and lukewarm milk. Add the yeast and mix to dissolve. Pour the liquid mixture into the flour mixture and stir until smooth.
• Crack in 1 egg and stir in the extra egg yolk. Mix gently to combine.
• In a separate clean bowl, whisk the egg white and salt until stiff peaks form. Use a spoon or spatula to gently mix the whisked egg white into the batter mixture. Cover and set aside to rest for 30 minutes.
• Heat a thin film of melted butter a shallow pan and, using a large tablespoon, drop small amounts of batter into the pan to make small (5cm) blini. Gently cook the blini until bubbles form on the surface (about 2 minutes), then flip and cook on the other side. Repeat until the blini batter is used up (keep the cooked blini warm).
• Serve the blini topped with a spoonful each of sour cream and caviar, garnish with dill and enjoy with champagne or iced vodka.

Tip:

You can also make the blinis in advance and freeze them. To do this, stack them with a piece of baking paper between each one so that the blinis don't get soggy. Bake from frozen in the oven at 220°C for 7 minutes.
