This large pan has a layer of clean sand on the bottom (about 1cm thick) on top of that I placed a metal disc (from one of my loose bottomed baking tins) to make sure that anything in the 'oven' won't get covered in sand.
So we made some Lemon Poppy Cake, as we only had 2 eggs, we used Chia seeds as egg replacer for the other 2 eggs.
This recipe did not call for baking powder but think it would be good to add 1 teaspoon to the selfraising flour. We made sure that after greasing and flouring the jars (Ball kilner jars as they have straight necks) we filled them half full with the batter. We then placed them (without lids) into the 'oven'. When the oven was hot, we turned down the gas to low and cooked it until risen and firm. Once done, we removed the jars and added the lids so that when they cooled down, they would close in a vacuum and can be kept in the larder for weeks to use when unexpected guests arrive. The one that was rather full, I let cool down and took out of the jar to cut into round slices with a cup of tea.
For Lunch we made Quorn Chicken pieces chasseur,
Together with some rice and some salad from the garden (various leaves, including, lambslettuce, rocket, chickweed, beetroot leaves, carrots, and peppers) we turned these goodies into a delicious lunch.
