The lab notes
The science behind every step
Restaurant cooks do these things by habit. Here’s what each step is actually doing to the food, so you can cook by understanding instead of guesswork.
Lab note01
Why overnight
Soak at least 8 hours.
Day-old bread is drier and absorbs custard slowly; a long soak lets it reach the center so the casserole bakes evenly custardy, with no dry middle.
Lab note02
Bake to 160°F
Check the center reaches 160°F.
Egg custards set around 160–170°F; 160°F is also the safe temperature for egg dishes.
Lab note03
Cold butter streusel
Rub cold butter into the streusel.
Cold butter stays in pieces that melt in the oven, frying the flour and sugar into crisp clusters.
How to make it, at a glance
- AssembleButter a 9×13-inch dish. Layer half the bread, half the blueberries and the cream cheese, then the rest of the bread and blueberries.
- CustardWhisk the eggs, milk, cream, brown sugar, maple, vanilla, cinnamon and salt and pour evenly over the bread, pressing it down. Cover and refrigerate overnight.
