Put in the effort; mix in the ingredients and wait for the cake to rise- keep the oven door shut. If need be turn on the light to watch the wait occur, concur with yourself time and again and repeat the thought and its implications and complications and re-study the information already gathered.
Recipes only go right if you don't follow the measurements, so pour a little more than need be, kneed a little longer, forget everything learnt and be yourself around her.
