The raw kumquat (mini orange, dwarf orange) has a certain sweetness and tastes slightly bitter. Prefer organic, as it is edible with the peel and seeds.
The Brazilian guava (feijoa, pineapple guava) is edible raw. Its taste and aroma are reminiscent of pineapple. Organic feijoa can be eaten with the peel.
Conventionally produced guava nectar and guava juice are preserved, therefore not raw. Rarely available in organic quality. Lots of sugar and little vitamin C.
