Fold the garlic through the blini mixture. Heat a lightly greased, non-stick 18cm-frying pan over medium heat. Spoon half of the blini mixture into the pan and spread to cover the base. Cook for 3–4 minutes or until bubbles appear on the surface. Flip and cook for a further 3–4 minutes or until golden. Repeat with remaining blini mixture. Allow to cool.
Place the mayonnaise and lemon rind in a bowl and stir to combine. Spread one of the blinis with the mayonnaise mixture and top with fennel, basil, chicken and chives. Sandwich with the remaining blini, cut into wedges and serve with lemon. Serves 4.
