minute maid is a brand we used to use in Canada but I've searched and searched, even on 'Ex Pat' sites but no luck -its a shame cos i too have some nice recipes using the concentrated juices and the Tropical juice makes a cracking addition to Sangria
I remember frozen Florida Orange Juice very well - it was one of the very few I liked. Most orange juice contains orange oil from skin of the oranges from the pressing process. It gives those juices a bitterness I can't stand. You could try the Co-op's 'Not from concentrate' orange juice, 'smooth' or 'with bits', at £3 for two 1litre cartons. It's pretty good.
