When I was a kid, raisins were everywhere. My parents were very into the 70s / 80s wholefood, grow-your-own thing, so we never had sweets or chocolate (except cooking chocolate) in the house. We had raisins (Nanna had sweets though...).
Breakfast was bran flakes or weetabix with raisins (plus extra wheatgerm). We had those little red boxes of raisins in our lunchboxes. Baking usually had raisins in it - chocolate was for birthday cakes. Puddings were almost always fruit based as well (e.g. stewed damsons with custard).
To this day I love dried fruit, especially the extravaganza of it at Christmas.
Are raisins still big? I suppose there's anxiety about the sugar content now, but they have loads of fibre, which possibly compensates.
