Place corn, in the husk, in the microwave and cook on high for 2 minutes per ear. Let cool and then cut the kernels from the cob.*
Remove the sorrel from the stem and rip into bite sized pieces. Place in a bowl.
Cut the tomatoes in half or quarters (depending on their size) if using baby tomatoes or slice the tomatoes if using the large heirloom variety. Place in the bowl and sprinkle with sea salt. I like Maldon, but any good quality sea salt will do. Let the tomatoes "sweat" for a minute or two. **
Add the corn, olive oil and fresh herbs if using. Toss and taste. Add more salt or herbs or olive oil if needed. Serve. ***
