I’ve made a lot of escabeche in my time, and read scores of recipes from all over the world. This vinegary, bracing sauce make a perfect summer lunch or dinner and is ideal for weekly lunches because escabeche keeps for days in the fridge. It’s one of my go-to dishes when the heat arrives.

But escabeche is often a hub of controversy. Who invented it? What is a “real” escabeche and which versions are poseurs? Is it a fish dish or a meat dish? Debate even surrounds the dish’s pronunciation: Es-kah-BAY-chay, Es-kah-BEH-chay or Es-kah-BESH?

The answer to all of these questions is “it depends.”

Scholars say Arabs invented the technique of cooking a meat or fish and sousing it with a vinegary sauce, probably sometime in the early medieval period. Then again, the ancient Romans were particularly fond of vinegar sauces, so I personally would put my money on either them, or the Greeks who preceded them, as the inventors.

In its modern form, escabeche is a Spanish creation, and this is the country I turn to for my own escabeche. The Spanish in turn spread the dish all over their empire in the 1500s, and what has emerged over the centuries are subspecies of the Spanish escabeche in Mexico, South America and the Philippines — and then there are the Portuguese, who can also lay legitimate claim to the dish, although every Portuguese escabeche I’ve seen has been pretty plain-Jane.

Why bother doing this? Because meat prepared this way will keep for days, even weeks if the weather is cool. And as it is most typically made with game birds or fish — both things that you can have a surfeit of after an unexpectedly good day — so semi-curing the meats makes a lot of sense.

There is another element to escabeche that needs mentioning: It is a surpassing dish for lean game birds, as the olive oil and vinegar-wine sauce keeps everything from drying out. I used a morbidly obese pheasant Holly had shot last season at a preserve for this escabeche — and while I enjoyed eating all that pheasant fat, I am pretty sure it would put off a civilian.

Red-legged partridges, or perdiz, are the classic Spanish escabeche bird; the closest thing we have to them here are chukars. That said, I have read Spanish recipes for cordoniz (quail) and faisan (pheasant), as well as American versions with the very dull Cornish game hen. If you are not a hunter and want to make this dish, please — for me — buy either a really good chicken and cut it up, or farm-raised quail or pheasants. It’s worth it.

Yes, fish escabeche is also very common, and in fact I made an Italian version of this called scapece on Sunday. It is simpler than the Spanish escabeche, and is designed to be used with oily fish such as mackerel, herring, bluefish, or, as I did, sardines. Here is the recipe.

As you can tell, the key difference between the more common seviche (also spelled ceviche) and escabeche is that you cook — often fry — the meat before it hits the vinegar sauce. That helps with the preservation and also makes sure your game birds are falling-off-the-bone tender.

I decided to switch things up this time and grill the pheasant. Normally this would have been a great idea, but with the Morbidly Obese Pheasant, fat spattered on the grill and I nearly had a grease fire on my hands. No bueno. Still, I got good color and flavor from grilling the pheasant and will do this again, especially because I can do it easily now with a gas grill.

Given all the idiosyncracies of regional escabeches, know that at least in a Spanish version there are some ingredients that must be included:

• Olive oil
• Vinegar (usually sherry)
• Thyme
• Bay leaves
• Lots of garlic
• Onion
• Black pepper

Other common ingredients include paprika, carrots, celery, parsley, rosemary, cloves and oregano. A few include olives and, as I do, saffron.

Again, regionality. Mexican escabeche uses fruit vinegars or lime juice. Portuguese versions use cider vinegar, Italians wine vinegar. Chiles or no? Mexicans and Italians say yes, but I rarely see hot chiles in either Spanish or Portuguese versions. I leave them out, as they compete with the saffron.

How hard is escabeche to make? It’s not simple, but nor is it any great feat to pull off. Mostly it takes time to get the proper browning on the bird and in simmering to get it tender. My full recipe is here.

Oh, and I know what many of you are thinking: Why not pull the meat off the bones to make it easier to eat? Yeah, I know I could. But I like getting into my food, and this sharp, rich sauce makes eating the pheasant a more primal joy. Besides, I like wiping the grease off my chin.
