The tomatoes were actually homemade, and dried in the oven. I might actually try drying them in the sun one of these days as it does take a lot of electricity (low temperature for up to 6 hours) but I'll need to purchase some screens - don't you need something to keep the bugs off of them considering it takes a few days? A friend from work suggested using a dehydrator as well (I recall having three of those at one point; none of them being used)!
Anyway, I oven dried a batch of my homegrown tomatoes earlier this year and had stored them in the freezer until now.
Usually if I make a large enough batch I'll store some in the freezer, but will also keep some in a jar in the fridge with a bit of olive oil; the oil absorbs some of the flavour so the oil can be used for cooking as well.
Oven-Dried Tomato and Pepita Pesto
In a food processor, combine and process the following:
2 garlic cloves
1 tightly packed cup fresh basil leaves
1/3 cup pepitas
1/2 cup oven dried or sundried tomatoes
After the ingredients are minced, continue processing and drizzle in 4-5 Tbsp olive oil (you might need a bit less if you have used sundried tomatoes from a jar that already have a bit of oil on them).
Remove from food processor, and stir in 1/4 - 1/2 cup parmesan cheese. Season with salt to taste. Makes enough for 4 servings of pasta. Toss with hot pasta along with some of the cooking water.
