Rhubarb filling:
– 2 cups rhubarb stalks cut the width of your rectangular tart pan or the diameter of your round tart pan (if using)
– 2-3 TBs honey or maple, if making vegan
– Zest of half a lemon
In a large bowl, blend flours and salt. Add remaining ingredients and mix until a soft dough is formed. Shape into a ball and wrap in plastic wrap. Chill in fridge for about 15 minutes.
Place dough into tart pan. Arrange rhubarb stalks horizontally if using a rectangular pan, or going out like the spokes of a wheel if using a round tart pan.
