I'll say right now that I don't get free stuff from companies. I bought all of these at some point (apart from the one a friend gave me) and I'm reviewing them because I feel like it, not because I'm compelled to. But hey, if Alpro (or any other vegan company) wants to hook me up, I won't say no.
Both brands just call these things desserts, but if we were in the US, we'd be talking puddin' cups. Different countries have different varieties on offer. In the UK, Alpro offers vanilla, caramel, dark chocolate, and "smooth" chocolate (which I guess is meant to be like milk chocolate), while Provamel offers vanilla, chocolate, caramel and "moka" (according to their website - the package I have says cappuccino). But other countries might have other things - I know for sure that Belgium gets Alpro speculoos puddin' cups, the lucky bastards.
The good stuff.
So how are they? Well, I'll admit two things: a) I've never tried the vanilla of either brand as far as I can recall, and 2) I can never remember which of the chocolate varieties I like. That said, I quite like the Alpro caramel, though I prefer it mixed with chocolate. The Provamel moka/cappuccino is good on its own (though I don't know where they get off calling it moka, which implies chocolate, when there's no chocolate in it). And I think I like one of the Alpro chocolates, but I'm too cheap to buy both to figure it out because then I'll have a package of stuff I don't like (though I'm sure Mike would eat them). Of course, the standout winner is the speculoos stuff, but I've only had that once (well, one package of 4) because, like I said, it's only available in Belgium.
They're also kinda diet friendly, if you're looking for that kind of thing. My bff, who isn't even veg, loves the dark chocolate for a dessert, not only because it's tasty, but because it usually fits within her calorie budget. (I can also confirm that the Alpro Light Chocolate Soya Milk works well if you need a hot chocolate fix but don't want to consume 500 calories in one cup.)
I'd definitely recommend giving these a try. They're usually pretty tasty, not too bad for calories, and almost always on sale somewhere (at least the Alpro ones are - usually 2 for £2.50 at Sainsbury's and/or Tesco).
*Thanks for clearing that up, Professor Wikipedia! Also, they're from Belgium, which is why the Belgians get all the good stuff first.
