Common Mistakes to Avoid
Making French Onion Sausage Rolls can be fun, but a few common mistakes might affect your results.
-
Skipping the caramelization: Failing to properly caramelize the onions can lead to a bland filling. Cook them slowly for about 20 minutes to enhance their flavor.
-
Overfilling the pastry: Adding too much sausage mixture can cause the rolls to burst while baking. Use just enough filling to allow for folding and sealing without overflow.
-
Not sealing edges properly: If you don’t seal the pastry edges well, they may open during baking. Use water to dampen the edges before folding to ensure a tight seal.
-
Using cold pastry: Cold puff pastry can be difficult to work with and may not rise as well. Let it thaw completely at room temperature before rolling it out.
-
Skipping the egg wash: Not brushing your rolls with an egg wash can result in dull, unappealing pastries. Brush the tops with beaten egg for a shiny, golden finish.
