Fairy Glen cookies are an excellent option when you want or need gluten-free cookies. They do, however, require almonds, so if you need to accomodate someone with a nut allergy, these aren't for you.
Fairy Glen Cookies
3 egg whites
1-3/4 cup (350g) sugar
3-1/3 cup (330g) finely ground almonds
1/4 cup (60g) orange marmalade, melted
20 candied cherries, halved
Beat the egg whites and salt to soft peaks, then add the sugar and beat to stiff, glossy peaks. Fold the ground almonds into the whites, then fold in the melted marmalade.
Pipe the mixture as 1½" (4cm) rosettes onto buttered cookie sheets, spacing 2" (5cm) apart. Top with half a candied cherry.
Bake in a 350°F (180°C) oven until golden, 10-15 minutes.
