That's oven-dried tomatoes. Yesterday, I chose seven nice tomatoes from the garden.
Here they are.
Remove the stems and cut each tomatoes into just four wedges. Arrange them on a pan so that they are not touching each other.
Set the pan in the oven pre-heated to 90ºC / 200ºF. Leave it there for eight hours. Turn the oven off and let the tomatoes cool down and continue drying for another few hours (overnight). Here's what you get.
Advantages: the tomato flavor is really concentrated, and slightly caramelized. The dried tomatoes can be stored in a sterilized jar over the winter. They don't take up much space.
I should have done seven more tomatoes. Maybe this weekend.
