Ask for help

A question at the stove — how do I cook this cut, why did that sauce split, what's making it taste flat? Koji reasons it through with you, at whatever depth you want — the principle, the feel, or the exact temperatures — grounded in the recipe you cooked and the notes you took.

Give feedback on how it went and Koji can keep the lesson as a skill it applies the next time you cook something like it. The more you cook, the more it knows.

I want to make my peach & Darjeeling ice cream again, but the last batch coated the roof of my mouth. Can we fix that without losing the tea?

Your cook log says exactly that — “coating the roof of the mouth” — so let’s fix the base, not the flavours. The coating is a fat problem: your v3 base is 946 ml of 36% cream plus 11 yolks, a very heavy anglaise. Rebuild it on a buttermilk custard: the fat drops sharply, so the coating goes — and buttermilk’s lactic acidity sharpens both the peach and the Darjeeling rather than muddying them.

Won’t less fat make it icy?

It will if you change nothing — the fat was hiding the water. Hold back some of the cream rather than all of it, add a spoon of glucose to depress the freezing point, and churn it colder. Want me to update the recipe with these changes? Nothing changes until you confirm.
