Deviled eggs are a classic picnic snack prone to an all-too-common problem: a greenish colored yolk and a sulfurous odor. What causes the problem and how do you make perfect deviled eggs every time? Here’s what we discovered:

Test Kitchen Discoveries

• Don’t boil the eggs. After countless tests, the test kitchen found it best to cover the eggs with an inch of water, bring to a boil, cover, and remove from the heat. After 10 minutes, drain the eggs and cool in ice water. The gentle heat perfectly cooks the eggs—not a chance of the green tinge or unpleasant smell.
• For the creamiest texture, force the yolks through a fine-mesh sieve before mixing with the filling ingredients.
• For an elegant appearance, pipe the filling into the egg white shells with an impromptu pastry bag prepared from a zipper-lock bag. Simply place the filling in the bag, squeeze it tightly into one corner of the bag, and snip 1/2 inch off that corner. The filling can also be stored this way, at the ready, for up to two days. Just don’t cut the bag until you’re ready to fill the eggs.

To center the yolks, turn the carton of eggs on its side in the refrigerator the day before you plan to cook the eggs.

This recipe can easily be doubled. If only celery salt is available, use the same amount but omit the addition of salt in the dressing. When testing the potatoes for doneness, simply taste a piece; do not overcook the potatoes or they will become mealy and will break apart. The potatoes must be just warm, or even fully cooled, when you add the dressing. If you find the potato salad a little dry for your liking, add up to 2 tablespoons more mayonnaise.

This variation of our All-American Potato Salad was published in our cookbook The Best Make-Ahead Recipe.

Because the spiciness of jalapeños varies from chile to chile, we try to control the heat by removing the ribs and seeds (the source of most of the heat) from those chiles that are cooked in the rice. Use an ovensafe pot about 12 inches in diameter so that the rice cooks evenly and in the time indicated. The pot’s depth is less important than its diameter; we’ve successfully used both a straight-sided sauté pan and a Dutch oven. Whichever type of pot you use, it should have a tight-fitting, ovensafe lid. Vegetable broth can be substituted for chicken broth.

In addition to serving this salsa with tortilla chips, you might try mixing it in with pasta—about a tablespoon or so per serving. You’ll still get a good dose of heat.

Add the orzo to the boiling water a couple of minutes before slipping the pork chops into the hot oil.

Bland supermarket button mushrooms shrink and shrivel when sautéed. We wanted more flavor and more mushrooms.
