Pickle

Use small organic pumpkins or squashes. Before peeling, taste their skins. If they are very tender, they can be left on. Pickled pumpkin is good served with crispy roast pork seasoned with five-spice or on its own as part of a pickle plate.

There were always barrels of pickles at the flea markets my parents took me to when I was growing up. My dad loved half-sours; my mom loved sweet pickles; I loved both. Mom would cut both kinds in half and stick them together, so I’ d get two flavors in every bite. This is my homage to those days, made with one of my favorite ingredients.

Pickled onions such as these are most often used as a garnish for tacos, burritos, and guacamole in Mexican cuisine. I think they are just as delicious on most of the burgers in this book, and they add a level of intrigue that raw onion slices could never do. The fresh lime juice is essential for its fresh, clean flavor as well as its acidity. If you want to pump up the volume on flavor and add a bit of heat, try adding a few whole jalapeño or serrano chiles to the mix.

I love the spicy, vinegary punch of pickled jalapeño chiles. There’s no need to reserve these for nachos only; this pickle goes well with any Mexican- or Southwestern-inspired dish—and that includes burgers—that could use an acidic touch of heat. It’s simple to make your own, and I think you’ll find that the freshness of home-pickled jalapeños beats any jarred or canned supermarket version, hands down.

As a New Yorker, I have ready access to some of the best dill pickles out there. Even so, I still like to whip up a batch of my own every now and then. It is really very easy to do, and you have total control over the flavor and seasonings. If you really like garlic, toss in a few more cloves; if you prefer your pickles on the spicy side, add a couple of pinches of red pepper flakes. This is a basic recipe and you should feel free to experiment with other spices, too, such as cumin or fennel seeds. One note: though light on labor, this is not a last-minute recipe. The cucumbers need to “pickle” for at least 24 hours to get the best flavor.

There is not much to peel in celery, just the strings that run along the ribs that can be annoying to eat. To remove them, I take a peeler and lightly run it along the back of the celery rib. Another way to remove them is with a paring knife. When you are trimming the base or the top of the stalk, don’t just chop away, but gently hold the stalk in your hands and cut from the inside of the stalk to the outside without cutting all the way through. Just before finishing the cut, pull the knife toward you and the strings should peel off down the length of the stalk.

If you like, trim the stems of the mushrooms even with the caps—they will look neater that way. Save the stems for vegetable stock or chop them for a vegetable soup. The mushrooms keep for a few days in the refrigerator. If you want to keep them longer, top them off with enough oil and vinegar to cover them completely. The oil will float to the top and seal out air. They’ll keep a couple of weeks like this.

When we think of kimchi we tend to picture the classic kind found in Asian supermarkets, which is made primarily with Napa cabbage stained red from the chili powder and pungent with garlic. Interestingly, although that is indisputably the most popular variation, kimchi can be made with a wide array of vegetables and spices, with regional variations that affect the ingredients used and levels of heat and spice. Here we’ve used red cabbage for two reasons. The first is because we like its sweet flavor and slightly sturdy texture. The second, more practical, reason is that these fermented pickles are generally deemed ready when enough lactic acid is produced to change the pH from 6.5 to approximately 3.5. Red cabbage juice changes color at this pH and becomes a bright reddish-purple, giving you a visual cue when fermentation is complete. Kimchi is a surprisingly good condiment for grilled hot dogs. It is a great way to doctor up packaged ramen at home. In place of coleslaw on a sandwich, it can add an unexpected kick to anything from corned beef on rye to pulled pork on soft white bread. Its heat and tang are wonderful for cutting through rich ingredients, and as a substitute for sauerkraut in choucroute, it is utterly delicious.

This popular Lebanese pickle is served as a mezze. Make sure the walnuts have a fresh taste.
