Pepperfruit vs Grains of Selim
The short answer
Two hot fruits of the custard-apple family from the West African forest, both called pepper in English, used in different ways. Grains of Selim are long dark pods of a tall tree, dried, often smoked, and simmered whole in soups and drinks. Pepperfruit is the small fruit of a forest shrub, green ripening red, mostly chewed fresh and offered to guests in southern Nigeria, and only secondarily cooked with.
Side by side
| Pepperfruit | Grains of Selim | |
|---|---|---|
| Botanical identity | Dennettia tripetala Baker f. | Xylopia aethiopica (Dunal) A.Rich. |
| Part used | fruit, seed | fruit, seed |
| Origin | A forest plant of West and west-central Africa. Herbarium specimens place it from Guinea to Cameroon. | The savanna and forest-margin belt of tropical Africa, with the species distributed from Senegal to Ethiopia and south into Tanzania. |
| Flavour notes | peppery, pungent | musky, resinous, bitter, eucalyptus, woody |
| Heat | Scoville does not apply | Scoville does not apply |
| Flavour | Hot and peppery. Every source read describes the fruit as spicy and says that is why it is eaten; none measures the heat. | Musky, resinous and bitter, with the pungency concentrated in the seeds rather than the pod. The pod carries the aroma and the seed carries the bite, which is why some preparations use whole pods and remove them and others crush the lot. |
| Aroma | Strong and characteristic, in the fruit and in the bark alike. The sources read do not describe it further, and no tasting panel was found. | Resinous and musky, with eucalyptus and a bitter woody edge — sources describing it reach for cubeb and nutmeg together, with resin over the top. It is markedly more medicinal than black pepper. |
Which should you buy?
Pepperfruit
Sold whole, fresh in season and dried out of it. Nothing read describes a ground product.
Grains of Selim
Whole, decisively. This is one of the clearest whole-versus-ground cases in the catalogue, and the reason is not shelf life but what gets into the dish: the aromatic fraction is in the pod wall and the bitterness is in the wood, and the traditional technique of crushing lightly, bundling and removing extracts the first while leaving the second behind. Ground grains of Selim puts both in, which is right for coffee and wrong for a soup.
