The notion that some foods provide comfort is probably as old as the adult child of the first cook, who, having a bad day, prepared some dish remembered vividly from childhood. It’s likely that the dish was high in fat and carbohydrates, filling and satisfying.

What that dish might actually be, of course, may depend on your gender — women tend to prefer sweets and snacks, while men prefer hearty, meaty dishes such as casseroles and stews. Or so say the scientists who study such things.

It will also depend on your culture — the dumplings of China, Armenia and Poland may provide scant comfort to the Latino who’s looking for Puerto Rico’s arroz con gandules, rice with pigeon peas, or to the Indonesian for whom nasi goreng, fried rice with a variety of garnishes, speaks of home.

Most of us here in the States would recognize macaroni and cheese as a comfort food; so, too, mashed potatoes and pot roast and chicken pot pie and meatloaf and even birthday cake.

What these dishes have in common is their humble rusticity. These are dishes that we may remember our mothers and grandmothers preparing — good food served at their tables.

Comfort foods share another commonality: They are typically something we ate early in our lives, perhaps the first time we became fully aware of the food we were eating. These dishes echo, whether or not we consciously realized it, a time when we knew beyond question that someone cared for us — because whenever someone feeds another person, at the act’s base is the wish to provide sustenance. The person who places food in our hands says by that act, “I want you to live.”

Preparing a comfort food from your childhood is a Proustian resurrection of those who cared for you in the past. If they are dead, the dish’s preparation may be wistful or poignant, but it is a resurrection, a recalling of those lives into your own.

For this reason, comfort foods are often idiosyncratic. A dish often has a meaning for you that it has for no one else.

I am the daughter of Bobby Hughes Mather, dead now for nearly two decades and missed every day. She was a difficult, brilliant woman whose generosity and skill as a cook were unparalleled. She fed her family of seven — and the frequent guests at her table — with grace and talent. This is the dish I cook for myself when I want to resurrect her.

OXTAIL STEW

Prep: 30 minutes

Cook: 3 hours, 15 minutes

Makes: 4 servings

This is good the day it’s made but better if you can wait to serve it the day afterward. Refrigerate overnight, of course.

1 cup flour, heavily seasoned with salt and pepper

3 pounds oxtails

2 tablespoons olive oil

2 cloves garlic, smashed, minced

1 large onion, halved lengthwise, sliced into ¼-inch slices

1/2 cup red wine

2 cups diced tomatoes with juice, or 1 can (14 ounces) diced tomatoes

1 to 2 cups beef broth

2 bay leaves

1 teaspoon dried thyme, crumbled

1/2 teaspoon dried rosemary, crumbled

1 pound carrots, peeled, cut into large chunks

3 pounds potatoes, scrubbed, cut into large chunks

1. Place the seasoned flour into a large zip-close bag. Working in batches, add the oxtails, and shake to coat them generously with flour. Transfer the floured oxtails to a plate; discard the flour.

2. Heat the oil in a large Dutch oven over medium-high heat. Working in batches, add the oxtails and brown them on all sides, about 3 minutes per side. Transfer the oxtails to a plate and set aside.

3. Add the garlic and onion to the Dutch oven, and cook, stirring frequently, until the onion is softened and translucent, about 5 minutes. Add the wine, and stir to scrape up any browned bits. Cook until the wine has almost evaporated, about 5 minutes.

4. Return the oxtails to the pot. Add the tomatoes and enough beef broth to cover. Break the bay leaves in half and tuck them between the oxtails. Bring to a boil, decrease heat to a simmer, cover and cook until the meat is tender, 2 to 2 1/2 hours.

5. Add the carrots and potatoes. Cover and simmer until vegetables are tender, 45 to 60 minutes longer. Remove the bay leaves and serve.
