Preheat the oven to bake 180 degrees celsius. Grease a non-stick 23cm loose base quiche or tart tin with butter.
In a mixing bowl, combine the almond flour, gluten-free flour and salt. Mix together. Add melted butter and the first measure of runny honey (2 Tbsp). Mix until crumbly.
Whisk the egg and add to the crumbly mixture. Mix until a dough forms.
Press dough into the quiche tin, taking time to get it nice and even. Prick holes with a fork into the base.
Bake for 10-11 minutes. Keep an eye on it over the last few minutes as the top can quickly burn. Once cooked, remove from the oven and let cool for ten minutes before very CAREFULLY removing from the tart tin (it's delicate!). I do this by pushing up the bottom so the side is released, then sliding a wide spatula between the tart case bottom and the crust to release it.
