The green cheesecake didn't look particularly green (actually kinda grey) but it did taste pleasantly tea like. These muffins had a much more exciting colour, but unfortunately a very mild taste. They were pretty good anyway.
On the subject of frugality, matcha powder isn't cheap. However, most recipes only call for small amounts, so now I've got some, I think I'll be experimenting for a while...
Green Tea Muffins
2 C Self Raising flour
1/2 C Sugar
2 teaspoons matcha powder (Japanese powdered green tea)
1 C skim milk
90g melted butter
Heat the oven to 180 degrees Celsius. Grease the muffin tins (this recipe makes about 15 muffins). Sift the dry ingredients together. In another bowl, mix the wet ingredients. Add the wet ingredients to the dry with as little stirring as possible. Spoon into muffin tins and bake for 20 minutes, or until golden.
These muffins are not very dessert-like. They are more like scones or rock cakes in consistency, but still quite sweet.
