Basically a form of grape, but dried, raisins do however hold their own distinct flavour profile.
"Raisin", in the UK specifically refers to a large dried dark grape, while we use Sultana for a dried white grape and Currant to describe a dried black corinth grape.
Widely used in cooking, mainly in desserts, owing to their high level of sweetness they also lend themselves very easily to infusions. The simplest method being to let the raisin soak overnight in the base spirit.
Less know for being used as a fresh muddled fruit, the flavour can be intense and overpowering, but sits very well with rose, oak, or citrus notes.
(Dried large dark grape variety) Flavour - Sweet, rich, succulent.
