Parece que os cookies Hamantaschen se desdobrando e vazando não é um problema incomum. É claro que a substituição do ovo de linho pode muito provavelmente também contribuir para o desdobramento, mas aqui estão algumas dicas de alguém que vem fazendo biscoitos Hamantaschen por um tempo.
Dicas para criar hamantaschen perfeitos
1) Find a great dough recipe. Often, the problems people have with baking hamantaschen can be traced to an inferior dough. Here are two foolproof, tasty dough recipes that I highly recommend. They are easy to handle and shape, and they provide great results when baked:
É claro que você pode usar o seu ovo de linho para substituir os ovos que as receitas pedem.
2) Roll your dough out to 1/8 inch thick (or less). You want your dough to be as thin as possible, while still being thick enough to maintain the cookie’s structure. 1/8 inch seems to be the magic number; sometimes I roll mine out even thinner than that. For a more doughy texture you can roll it thicker, but remember– the thicker the dough is, the harder it will be to handle and shape. Thick dough is also more prone to opening/spreading in the oven.
3) Use a thick filling that won’t run/weep from the cookies while baking. Knowing the proper consistency of a hamantaschen filling takes experience, because each type of filling is slightly different. Poppyseed filling has a very different texture than fruit filling, for example. A good filling should be somewhat thick so that it doesn’t run.
4) Cut your hamantaschen dough in 3-inch circles (or larger) before filling and folding into triangles. Anything smaller than 3 inches will be difficult to fold around your chosen filling.
5) Most fillings can be chilled before using to fill hamantaschen. I’ve found that fruit, poppy seed, and cream cheese-based fillings tend to be easier to work with when they’re chilled in the refrigerator. The chilling process thickens the fillings and makes them less sticky, which makes them easier to handle with when you’re assembling your hamantaschen. Not all fillings are helped by refrigeration, however– particularly chocolate-based fillings like Nutella, which will harden with prolonged refrigeration. Check your filling recipe to see if refrigeration is recommended.
6) Do not overfill your hamantaschen. Use 1 teaspoon of filling per hamantaschen cookie. Do not use more than 1 teaspoon. However tempting it might be to put lots of delicious filling in the middle of your cookie, using more than 1 teaspoon can cause your hamantaschen to spread open and leak in the oven. 1 teaspoon is plenty, especially when you cut your dough circles to 3 inches… it’s the perfect amount of filling.
7) Fold your triangles the right way! Using the proper folding method will help your hamantschen hold together and create a beautiful shape.
Por favor, que os lados sejam dobrados para baixo, de modo que cada "lado" tenha um "fim" acima e um "fim" que fique abaixo do modo de dobrar o topo de uma caixa. Isso ajudará a impedir que os cookies se desdobrem.
