Preheat the oven to 150*C
Line a baking tray with baking paper
Gently whisk the eggs whites and the salt until soft peaks form
Combine the egg whites with the almond meal, caster sugar, apricot jam and lemon zest.
Transfer spoon sized batches of the mixture onto the baking paper, and then sprinkle with flaked almonds. Alternatively, you can use a piping bag and create little logs, which can then be sprinkled with falked almonds.
Baked for 10-15 minutes.
Once baked, spread apricot jam on one biscuit or log and sandwich it with another.
