Gotchas — read before the oven goes on
The freezer bowl is tonight's real deadline. If it isn't frozen solid by morning there is no churning tomorrow, and everything else you did tonight just sits in the fridge. Do it first.
Weigh the empty saucepan before anything goes in it. The reduction target is 350 g of purée, which you can only read as pan-plus-350. "Until it looks thick" is how you overshoot into canned-peach flavor.
Roast for color, not just for soft. Browned edges and caramelizing pan syrup are the flavor these peaches don't have on their own. Pale and soft means you simmered them in the oven.
Convection is the right call, at 375°F rather than 400°F. Moving air strips the humid layer off the fruit, so it dries and browns faster — which is the entire point of this roast. Spend that advantage on time, not temperature: at 400°F convection the sugar at the pan edges scorches before the fruit collapses, and burnt sugar is not a flavor you can dial back out.
No vanilla bean in this batch — extract only, and that is a deliberate trade. The audience is a six-year-old, and specks are the kind of thing a six-year-old refuses a bowl over. A scraped pod never gives up every seed, so an overnight steep sheds a few, and vanilla seeds are around 0.3 mm against a 0.5 mm fine mesh — straining is not a guarantee. A few flecks carries the same rejection risk as a lot of them for almost none of the flavor. What the pod would have bought is the woody, rounding low end, and under roasted peach plus a tablespoon of lemon that sits close to the noise floor. Good extract carries the same congeners with none of the risk.
Extract goes in cold, tomorrow, not tonight. Its aromatics ride on alcohol and heat drives them off. The cold base right before churning is both the best retention and the natural tasting moment.
The bean isn't wasted, it's reallocated. It stays whole in the pantry for a vanilla ice cream, where the flecks are the entire point and Maxwell already likes the result.
Strain unconditionally. Promoted from "only if it feels fibrous." Peach fiber that disappears in a warm purée reads as stringy frozen, and a homogeneous spoonful is what is actually being sold here.
All the pan syrup goes in the saucepan. Scrape the dish. That syrup is the most concentrated peach in the recipe and it is easy to leave behind.
Heavy cream is structural. The 390 g of dairy has to land near 27% fat and the cream supplies essentially all of it. Half-and-half cannot stand in — you'd need twice the volume and all that extra water is exactly what the roasting step exists to remove. The 100 g milk portion is the part where anything goes.
Season warm, confirm cold. Cold mutes acid badly. Aim a touch bright tonight and taste again before churning.
Two drops of almond extract. No more. The peach-amplifying trick turns into marzipan somewhere around the third drop.
Don't reduce the sugar. It is depressing the freezing point, which is most of what keeps this scoopable. Cutting it gives you a peach brick.
Nothing gets eaten today. Tonight ends at the fridge door. If that feels unfinished, it is the recipe working as designed.

After dinner: put the empty-pan weight and the actual lemon amount in the cook log while they are still in your head, then set last-cooked on the recipe once you have tasted the frozen ice cream — not tonight.
