I was given Sicoly frozen blackcurrant puree (Ingredients: blackcurrant, granulated sugar.) The taste is out of this world (the strongest blackcurrant flavor I've ever tasted short of eating them right off the bush - but those who've tried that know that that's usually not a pleasant experience), but the texture is ... like one big ice cube that has the shape of the box it came in.
I'm thinking of thawing it overnight in my fridge and then passing it through my ice cream maker just to get the texture of a sorbet. I'm not planning any additions.
Of course on the label it says in big "DO NOT THAW AND RE-FREEZE"... but I can't imagine how that could be an issue, as long as I keep it in the fridge during the thawing process and don't wait more than 24 hours to freeze it again.
