A few short notes on brownie baking, gathered from the questions readers ask most often.
Overmixing
Overmixing in one line: once the flour goes in fold, do not beat. Beyond the number, beating develops gluten and gives a tough brownie.
The primary source has the final word, and it is worth a minute to check it.
When in doubt, choose the simpler option first; it is the one least likely to need undoing. That is the whole of Overmixing for most readers.
Cutting
Cutting: the line most people need is fully cooled, ideally chilled. In practice, a warm brownie tears; a cold one cuts in clean squares with a hot knife.
That is a general note rather than a rule; check the current details before you rely on it.
Do the cheap checks before the expensive ones. Knowing this about Cutting prevents most mistakes.
Doubling a recipe
A short note on Doubling a recipe. The figure to hold onto is two tins not one deep one; what matters is that a deep slab never cooks evenly.
Treat it as a starting point; specifics change with the house, the school or the kitchen.
Write down what you find before you decide anything; it makes the next step obvious. In short, Doubling a recipe is worth a minute before you commit.
Double-boiler melting
If you are looking into Double-boiler melting, start here: a bowl over simmering water, not touching it. The point is that a microwave works in short bursts if you stir between them.
The primary source has the final word, and it is worth a minute to check it.
Keep the paperwork; it is the proof when something is queried later. That is the whole of Double-boiler melting for most readers.
Oven temperature
Oven temperature in one line: 170 to 180 C fan. Beyond the number, a hotter oven sets the edges before the middle cooks.
That is a general note rather than a rule; check the current details before you rely on it.
If something changes, note the date; patterns only show up with dates on them. Knowing this about Oven temperature prevents most mistakes.
Brown sugar
Brown sugar: the line most people need is for chew, white for crust. In practice, a mix of the two is the usual compromise.
Treat it as a starting point; specifics change with the house, the school or the kitchen.
When in doubt, choose the simpler option first; it is the one least likely to need undoing. In short, Brown sugar is worth a minute before you commit.
Eggs
A short note on Eggs. The figure to hold onto is room temperature for volume; what matters is that cold eggs seize melted chocolate.
The primary source has the final word, and it is worth a minute to check it.
Do the cheap checks before the expensive ones. That is the whole of Eggs for most readers.
Salt
If you are looking into Salt, start here: a good pinch, in every batch. The point is that it sharpens the chocolate rather than making them taste salty.
That is a general note rather than a rule; check the current details before you rely on it.
Write down what you find before you decide anything; it makes the next step obvious. Knowing this about Salt prevents most mistakes.
Figures are general guidance; the primary source takes precedence.
