Tips for the best Blueberry Streusel Bars
Browning your butter: Check out this detailed guide for browning your butter which includes a video - the key here is allowing your browned butter to come to room temperature so it is set like regular butter.
Fresh versus frozen: So fresh blueberries will hold their shape best and thicken into a jam type setting in the filling of these bars so definitely recommend stirring frozen blueberries through the sugar and corn starch and letting it sit for the sugar to have a little effect for 10 minutes.
Type of flour: TIf you live in the UK (as I do) or do not know the protein in your plain flour where you live then I recommend you do a little research. In the UK, due to the lower protein in plain flour which means it doesn't hold up as well as bread flour for a recipe like this. UK bread flour has almost exactly the same level of protein as US plain flour and this affects how easy it is to handle and how the baked bars will turn out.
