What to use instead of rocoto
Quick answer
The closest option is Scotch bonnet, rated situational. A substitution between species rather than within one, and it shows. Rocoto is Capsicum pubescens, the only domesticated chilli with black seeds and furry leaves, and it is genuinely distinct: thick-walled like an apple, juicy rather than papery, with a heat that arrives immediately and fades. Scotch bonnet supplies comparable heat and a fruitiness that is close enough to pass in a cooked sauce, and nothing supplies the texture.
It will not do for: Rocoto relleno, which is a stuffed fruit and depends entirely on the thick flesh; Any preparation using the chilli raw, where the juiciness is the point.

SituationalUse: ~0.5× by volume — About half the volume, tasting as you go. Rocoto heat is variable and arrives faster than most chillies.

Works for
- Cooked sauces and salsas where the flesh is blended
- Dishes where rocoto is one component of the heat rather than the subject
Does not work for
- Rocoto relleno, which is a stuffed fruit and depends entirely on the thick flesh
- Any preparation using the chilli raw, where the juiciness is the point
Why there is no second option: Nothing else is close. Rocoto is the only cultivated member of its species and its distinguishing features — thick juicy flesh, immediate heat, black seeds — are species traits rather than variety traits, so no other chilli has them. Habanero was considered as the other very fruity option and is further away in texture than scotch bonnet; bell pepper was considered for the flesh and has no heat at all. Where the fruit itself is the dish, the honest advice is to cook something else. Editorial judgement.
