These continental treats, reknown in Paris, are worth the effort.

Preheat oven to 100˚C. Line two large baking sheets with non stick baking paper and mark circles using a 4cm cutter.

Mix the ground almonds, icing sugar and red food colouring together in a bowl. In another bowl, whisk the egg whites with the powdered pavlova mix until firm peaks form, then fold in the almond mixture using a large metal spoon. Firmly tap bottom of bowl on counter to eliminate air pockets.

Transfer the mixture into a large piping bag fitted with a 1cm plain nozzle and pipe neat little mounds into the marked circles on the prepared baking sheets. Press the tops down lightly with a wet spoon if they peak too much. To stop macaroons from cracking, leave to stand for a good 30 minutes then bake them on the middle shelf for about 35 minutes, until they feel slightly firm.

Leave them on the baking sheets for five minutes, then slide them off onto a wire tray to cool completely. They should be crisp on the outside and a bit chewy on the inside.

For the filling, beat the butter, icing sugar and vanilla extract together until light and fluffy. Stir in red food colouring. Sandwich the macaroons together in pairs with small dabs of this filling just before serving.

Unfilled macaroons can be stored in an airtight container for up to 3 days and the filling can be made the day before.

Makes approximately 20.
