    Shared aroma: 2-nonenal (fatty, green).

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

What each ingredient does

Ohelos
Provide the main fruit flavor and the body of the jam.
Sugar
Adds sweetness and helps preserve the jam by binding water.
Lemon slices
Add acidity that brightens flavor and supports gel setting.
Guava jelly (in the method)
Adds sweetness and fruit flavor to the Ohelo sauce.

The step that matters

Removing the ohelos before they break. Cooking fruit too long breaks down its structure and pectin, turning the pieces to mush and dulling the fresh flavor. Pulling the pan off the heat as soon as the fruit starts to break keeps the texture intact.
