Sour cherries substitutes

The honest best answer for most of the year, and the one most home cooks in Central Europe use without a second thought. These are the same fruit, picked ripe and packed in water or light syrup, so the flavour and acidity are right where you need them. The only difference is texture: they are softer than fresh and will collapse more readily, which is ideal in a soup or a sauce and means a pie filling needs an extra tablespoon of flour or starch to hold. Reduce the drained syrup down to a couple of tablespoons and stir it back in, because it carries a lot of the flavour.

Best for

cherry soup and cold fruit soups, cherry pierogi, vareniki and dumplings, pies, strudel and cake fillings, sauces for duck and pork

Read the label. Cherry pie filling is a different product entirely, thickened and heavily sweetened, and it will make the dish sweet and gluey.

Just as good as fresh and available all year in most large supermarkets and every Polish or Russian grocer. They are already pitted, which saves the worst part of the job, and their flavour and acidity survive freezing almost intact. Do not thaw them for baking: put them into the filling frozen so they hold their shape and do not flood the pastry, and add a tablespoon of flour or two teaspoons of cornstarch per two cups to catch the extra liquid they release as they cook. For soups and sauces, thaw or not as convenient.

Best for

pies and tarts, cherry soup, cakes and clafoutis, dumpling fillings

Frozen cherries shed noticeably more juice than fresh, so a filling that looked right when raw can end up loose. Err on the side of a little more thickener.

This is the fix nobody explains to new cooks, and it makes the difference between a good dessert and a dull one. Sweet cherries alone taste flat and jammy in a recipe designed for sour ones, because you have removed the acid that was balancing all that sugar. Add lemon juice, or a teaspoon of cider vinegar, or a scant quarter teaspoon of citric acid per pound, and taste the raw filling: it should make you salivate slightly. Sweet cherries are also firmer and meatier, so they hold their shape rather than collapsing into syrup, which is better in a pie and worse in a soup.

pies, tarts and cakes, clafoutis and buckle, sauces where you can taste and adjust, summer, when sweet cherries are everywhere

Dark varieties like Bing give a deeper colour closer to Morello. Pale yellow-pink varieties like Rainier make a handsome fruit bowl and a wan-looking pie.

Sourness and colour are both spot on, which is why cranberries work so well in cherry-style soups and sauces. What changes is the character of the tartness: cranberries are astringent and puckering where sour cherries are bright and fruity, and they carry a bitter note in the skins, so the dish tastes sharper and less obviously cherry. They also stay grainier and pop rather than melting, which is fine in a sauce and gritty inside a dumpling. Use a bit less and sweeten a bit more, and half a teaspoon of almond extract nudges the flavour convincingly toward cherry.

Best for

cold fruit soups, sauces for pork, duck and game, compotes, winter baking when no cherries exist

Chop them roughly first, since whole cranberries stay firm long after the rest of the dish is cooked and their skins are tough. Red currants, sold frozen in most Eastern European shops, are an even closer match on acidity and are the traditional stand-in in Hungarian and Polish cold soups, though they are seedier and disappear into a puree rather than staying whole.

A genuinely good structural match, because rhubarb has real fruit acidity and it collapses under heat in much the same way sour cherries do, giving you the same slumped, juicy filling. The flavour is the trade: rhubarb tastes green, tart and faintly vegetal rather than of cherry, and the colour runs pink rather than deep red. Half rhubarb and half sweet cherries is the best of both, giving you cherry flavour with proper acidity. Half a teaspoon of almond extract nudges either version toward the marzipan note that sour cherry desserts traditionally have.

Best for

pies and crumbles, strudel, compotes and cake fillings, spring, when rhubarb is in season and cherries are not

Use only the stalks. Rhubarb leaves contain high levels of oxalic acid and should never be eaten.

The least good option and worth using only when the shops are shut. Jam is already cooked and heavily sweetened, so a pie made with it weeps and slumps, dumplings burst as the thin filling boils, and the whole dessert reads as sugary rather than tart. Cut the recipe's sugar hard, at least by half, add lemon juice until the mixture tastes genuinely sour, and if it is going inside pastry stir in a tablespoon of semolina or fine breadcrumbs to stiffen it. It is passable in a cake filling or as a sauce and poor everywhere else.

Best for

cake and torte fillings, glazes and sauces, swirling into cheesecake or babka

Sour cherry preserves, sold in Middle Eastern and Eastern European shops, are far better here than sweet cherry jam, since they were made with the tart fruit to begin with.
