Grease a 12 hole bundt pan ( you can use a muffin pan as well)
Whisk the egg whites in a medium bowl until just combined. Add sifted almond meal,gluten free flour, icing sugar, butter and rind. Whisk until just combined then divide the mixture evenly among pan holes.
Bake for 15 minutes then remove from the oven, allow to cool slightly, then turn out onto a cooling rack.
To make the glace, mix all the ingredients together then spoon over the cooled cakes and serve.
