I use tubes of Primula, you can get it in cheap food shops, sometimes for a quid for 2 tubes and it doesn't need refrigeration. I prefer the ham variety. I sometimes use parmesan too just to 'posh up' the cheesy goodness. I've kept that a week in a very hot pack and it was still perfectly good. Lidl do it at a decent price.
As great as army rations are, the instant coffee is designed to keep you awake not for enjoying a decent cup of joe. I like to carry camp coffee, as it tastes just right.
The new Knorr stockpot/ gel is a great alternative to powder sachets for soup, Custard powder is great when it comes to fruit cake or bananas. Lucozade powder is almost as good as screech but if anyone can find Kool Aid then it is worth carrying.
Can anyone suggest a easy way to make cheesy macaroni without using kraft.
