Solar oven second draft

Today we experimented with cooking a tomato lentil soup in the solar cooker. Dh built a sturdier plywood box exterior, and added a second car reflector panel, which also acted as a wind shield.

We put about 2l soup materials into a cast iron dutch oven at 9.30am, before heading out for a day picnicing with friends at a local pool.

Extra insulation was old cotton clothing from the rag bag.

We knew we were reaching reasonably high temperatures because there was serious condensation on the oven bag interior, and when the bag was tapped, the drops of water sizzled furiously and audibly on the dutch oven lid.
The resulting soup is delicious, though I need to give Grandad B some credit for supplying the homegrown tomatoes! The lentils were cooked to a mush, and the onion and tomatoes were very soft. I think there was a slight cast iron flavour, but I'm hoping that means extra iron content for us!

Tomorrow I'll try a zucchini soup.
