A real house goddess doesn’t throw anything away when cooks. If you're going to cook vegetables using this recipe, or just dry tomatoes, there are 3 ways you can handle tomato skin. First, you may freeze them and when you cook the broth add them along with herbs and spices. Second, fry in oil until crispy, dry on a kitchen paper and add to pasta or salad. Third, dry in an oven at 100-120°C, allow to cool and grind in a spice grinder into tomato powder. Sprinkle with this powder unsweetened yoghurts, potatoes, fried meat or vegetables, add to borscht or other tomato soups.
