Not heard of a friendship cake before? Neither had I! Herman is a sour dough conconction, which when given you to, you care for and feed for 10 days, before dividing into four portions, three for friends and one for yourself to bake into a yummy cake!
If Herman stops bubbling, he dies.
Herman's growth a day after feeding. Aww they grow up so fast!
Herman mach 1 ended his life as a lemon cake. I changed the basic recipe (on the instructions) by omitting the apples, raisins and cinnamon, and adding the rind of 3 lemons to the batter, and whipped up a 2/3 quantity of this microwave lemon curd recipe. I put 2/3 of the batter into the tin, followed by a layer of the lemon curd (even then I didn't use all of it, maybe 3/4) and then scooping the rest of the batter over the top.
You need to cook this sucker for a LOOONNNGGG time! I estimate about 2 and a half hours! It might be my oven.
However, the result is an extremely dense and moist cake. Even 3 days later it was still just as good. The top was super crunchy, and the lemon curd gave it a delicious tartness throughout the cake.
