Now I know this whole soaking thing is not brain surgery, but I post this as a reminder to myself. Softening sun-dried tomatoes as well as any dried fruit, is very easy.
I like to heat water in a small pot–not to boiling. Then I soak the sun-dried tomatoes for about 20 minutes. After that I dry them off with a paper towel and pick over them to remove any damaged parts or big stem areas. Then they are ready for chopping, slicing, packing them in olive oil with garlic and herbs, or whatever your little heart desires.
And here are they are all soft and warm out of the soaking water.
