This waste reduction lark doesn't have to be all vegetable soup and knit-your-own-yoghurt you know. Recently I found a couple of luxurious and delicious shop-bought puddings which might make you fearful for your waistline, but leave your bin resolutely slim.
Chocolate and Vanilla Cheesecake from those quirkily-umlauted people at Gü. Small but perfectly formed, these are cute glass pots of indulgence, with foil lids and a simple cardboard box to hold them. The ramekins can be kept and reused, for cooking or other purposes (ideal as tea light holders as they are quite thick).
Cartmel Sticky Toffee Pudding people. Their puddings come in a sturdy foil tray (easily reused or recycled), cardboard lid, and cardboard sleeve. And if I said that this was one of the most lip-smackingly, plate-scrapingly, more-please-ingly delicious things I have ever tasted in my entire life, that would be no exaggeration.
Don't get me wrong, I still love cooking and baking, but these two really are well worth a try if you want a real treat without going near a hot stove. And not a bit of plastic packaging in sight.
