The question was asked simply because Andromeda and I had been trying to think of ways to get coconut oil into our bodies and we don't really like the taste of it when it is used to cook meats or veggies. So, I suggested we try making shortbread with it.
So, we tried it and it was delicious.
I don't know about the proportions exactly:
250 grams of ghee
250 grams coconut oil
1 and 1/4 cup xylitol
1/2 cup d-ribose
Tsp salt
2 tsp vanilla
Almost 2 K buckwheat flour
Cream the oil/ghee. Add the xylitol and d-ribose and salt. Then add the vanilla. Cream until very smooth.
Start adding the buckwheat flour and mixing after each addition. It will probably take almost 2 kg. You want it to make a nice, softly firm ball but not too soft and not too firm.
Then, divide it in two. Put one half on a baking paper lined big cookie sheet (with short sides). Cover with plastic wrap or more baking paper. Have someone hold it steady while you flatten it into the pan with a rolling pin. Do the same with the other half. Then cut into bar or squares with a sharp knife before putting in the oven. (take the baking paper off the top, that's just to help roll it.)
Bake at about 350 F or 160 C for 30 to 45 minutes or more until you can see it is beginning to brown. Take out and let cool and the bars should separate nicely and stack attractively on a plate.
You can also add ground coconut if you like.
Warning: don't think that you can add any water. It just makes it like bricks. It must be just oil and flour, basically. No other liquids (except that bit of vanilla and you can omit that if you like, or use lemon flavoring.)
