I started with the big plum tomatoes. Dip in boiling water for a few seconss, until the skin splits, then plunge in cold water. Slip the skin off (or faff around trying to get it off), then cut the tomato into 1/4 inch slices. Dry the slices.
I realised that I should pribably have cored the tomatoes before slicing but, by the time I realised, it was too late.
I had four trays of tomatoes, which took a loooooong time to dry thoroughly. I now have a pot of crspy tomato bits, and a small tub of i'm-fed-up-waiting mostly dry bits.
I'm going to grind then and make some super concentrated tomato powder which I can add to tomato based dishes (ooh, and pasta. and bread).
The dehydrator is on again, with loads of sliced chillies.
I might do the catnip while we're in drying mode. I should have done it a week or so ago while the atmosphere was drier. It's surprising how much the ambient atmosphere affects the drying times.
