Notes & Helpful Tips for Success!
- You can find frozen baby peas in any supermarket. Do not buy the ones that come packaged for “steaming” or “microwave” use, because those are partially cooked and will not work with this recipe.
- Always use good-quality extra virgin olive oil. Look for olive oil that is a product of only one country, whether it’s Italy, Spain, or Greece.
- Avoid olive oils that are blended with oils from various countries. Those are cheaper and not very flavorful.
- Don’t leave out the capers! They are subtle but add a lot of flavor to the peas.
- Make sure the onions are finely chopped, they will sauté easily, even caramelize, and will flavor the peas.
- Baby peas are best in frozen packages, not in a can. Canned peas are too soggy for this recipe.
