Cooking from a Polish recipe, and the unit that is ten grams

Polish recipes measure in dekagrams, tens of grams, so a line reading 25 dag of flour means 250 and not 25. That one habit wrecks more translated Polish recipes than anything else. The rest is a metric cup called the szklanka and a pantry of packets that look German and are sized differently.

The dekagram: the unit worth ten of itself

A dekagram, written dag or the older dkg, is 10 grams, and Poland runs its kitchen on it. A recipe asks for 50 dag maki, 500 grams of flour, or 25 dag cukru, 250 grams of sugar, and the number on the page is a tenth of the grams you want. It is the Polish cousin of the Italian etto, which is 100 grams on the same idea, and the risk is identical: read the dekagram as a gram and every quantity comes out ten times too small, which past a couple of lines is not a recipe any more. Half a block of fresh yeast is 5 dag, so even the yeast is counted this way. The fix is a habit, not a conversion: whenever a Polish recipe gives a bare number with dag beside it, multiply by ten.

The szklanka, a metric cup with a lighter fill

A szklanka is a glass, and as a measure it is the 250 millilitre metric cup, printed beside the American cup in Polish charts so a reader can see the four percent gap. Older recipes sometimes mean a smaller drinking glass closer to 200 millilitres, so the age of the book matters here as it does with the Slavic faceted glass. What a szklanka holds is its own small table, and the flour figure sits below the Russian one for the same volume because Polish charts assume a lighter, spooned fill.

Sugar is the row to watch if you are comparing pages. Polish charts put a szklanka of sugar at 220 g; the New Zealand authorities behind our printable charts weigh the same 250 millilitres at 225. Five grams, two national tables, and neither is a typo.

The szklanka itself sits with the world's other cups on cup sizes around the world, and the faceted glass it resembles, with its own two fills, is on Eastern European measurements.

Three Polish packets that are not the German ones

A Polish recipe leans on packets the way a German one does, and all three of the common ones are a different size across the border. Fresh yeast comes as a 100 gram kostka in Poland, not the 42 gram cube a German recipe means; butter is a 200 gram kostka, not the 250 gram German block, so pol kostki is 100 grams; and Dr. Oetker's vanilla sugar is 16 grams in Poland against 8 in Germany, the same concentration in twice the packet. Read any of the three across the border and the amount is off by a factor. The yeast dosing, and why fresh converts to the instant dry in packets at about three to one while American active dry needs closer to two, is on the yeast converter; the butter block and its centimetre ruler are on our butter master.

The flour typ, the false friend that is not false

Polish flour carries a typ number, and for once a European number matches the German one instead of tricking you. Polish typ and German type both grade ash, the mineral left after burning the flour, so Polish typ 550 and German 550 are the same flour, unlike Pfund read as a pound or Stufe read as a gas mark. Typ 450 is soft cake flour, typ 550 the everyday poznanska near American all-purpose, typ 750 the chlebowa bread flour, and typ 2000 the razowa wholemeal. What the ash number does and does not tell you is on flour types, alongside the French and Japanese systems it half-matches.

Spoons, eggs and the fill

The smaller things transfer. A lyzka is a 15 millilitre tablespoon and a lyzeczka a 5 millilitre teaspoon, the metric pair, so they need no conversion, and Polish charts mark a level spoon plaska and a heaped one czubata, the distinction our heaped versus level spoons carries for twenty ingredients. Eggs come by the count, and a Polish recipe assumes the European size band, which maps to American Large rather than Medium, on egg sizes.

Twarog is not cream cheese

The one Polish ingredient with no clean American match is twarog, the fresh white curd cheese also called bialy ser, and it is the whole point of a sernik, the Polish cheesecake. Twarog is a quark, lower in fat than cream cheese and unsalted, closer to a drained cottage cheese than to the Philadelphia block an American recipe reaches for. Make a sernik with cream cheese and you get a denser, sweeter, saltier cake than the light and tangy one the recipe intends. Where a Polish recipe names twarog, a farmer's cheese or a pressed quark is the substitution, not cream cheese, and it is sold by weight in dekagrams like everything else.

A recipe, decoded

Read the opening of a ciasto drozdzowe, a Polish yeast cake, as it is written. One line uses the dekagram, two use packets sized the Polish way and one the szklanka, so it shows the whole page at once.

50 dag maki

500 grams of flour, not 50. The dag is the trap; multiply by ten.

pol kostki drozdzy

Half a block of fresh yeast, 5 dag or 50 g, the one-to-ten ratio a rich Polish dough uses on this much flour. The whole Polish block is 100 g, more than twice the German 42 g cube.

1 szklanka cukru

A 250 ml szklanka of sugar, about 220 g. Weigh it rather than trusting the glass.

1 kostka masla

One 200 g block of butter, the whole Polish kostka, not the German 250.

2 jajka

Two eggs, European size, so American Large. The recipe counts them, it does not weigh them.

Only the szklanka of sugar needs a scale, and only because the glass is approximate. The rest is arithmetic once you know a dag is ten grams and a Polish block is not a German one. That is the whole character of a Polish recipe: it is exact, in a unit and packets an English reader has to learn first.

Questions about Polish measurements

What is a dekagram in a Polish recipe?

10 grams. Polish recipes, older ones especially, count in dekagrams, written dag or dkg, so 25 dag of flour is 250 grams. Read as 25 grams it collapses the recipe, and it is the single commonest mistake an English speaker makes with a Polish cookbook.

How big is a Polish szklanka?

250 millilitres, the metric cup, though older recipes sometimes mean a smaller glass nearer 200. A szklanka of wheat flour weighs about 130 to 150 grams depending on the chart, so weigh where it matters.

Is a Polish yeast block the same as a German one?

No. The fresh-yeast kostka sold in Poland is 100 grams, while the cube a German recipe means is 42. Reach for a Polish block on a German recipe and you more than double the yeast, so check which the recipe was written for.
