Drain and rinse the corn really well. Pat dry if needed.
Add corn to a large mixing bowl.
Then add in the rest of the ingredients, the diced tomatoes, diced onion, sliced scallions, diced pepper, minced garlic, chopped cilantro, lime juice, and spices.
Stir well.
Chill 20 minutes for best results or enjoy right away.
Notes
Use cold vegetables for best results, or chill the salsa for 20-30 minutes before serving.
Rinse and drain the corn well so it's not watery.
Dice the serrano pepper finely so the heat distributes evenly. Remove seeds and membranes if you want less heat.
Don't skip the fresh lime juice. It's what brings it all together.
Chop cilantro fine so it mixes in instead of clumping.
Taste and adjust salt, pepper, and lime juice before serving.
This gets spicier as it sits because peppers continue releasing oils.
Use fresh corn on the cob if you prefer. Just cook the corn, then cut off the cob with a sharp knife. You will need about 5 ears of corn.
