Reading all of this is making me very hungry especially in this rainy weather!
I have a real sweet tooth one that I learnt from an old Zuid-Wester (Namibian). You can make it at home or in the park but it needs to be stored in the fridge to keep it sticky but not runny.
1 can of condense milk
2 medium bananas
2 - 4 cups of rice krispies
For something xtra:
Either chopped peanuts or peanut butter (you don't have to place the peanut in)
Skin the bananas and chop into rings and then halves. Mix bananas, rise krispies and condense milk together in plastic container that can fit in the fridge. Guess the amount of people eating on dessert if rice krispies are not enough just add more but be careful not to add too much.
Then mix in peanuts / peanut butter and place in fridge for at least two hours. The mix will set until it's not runny anymore.
WARNING VERY SWEET! We love eating this and it lasts between 4 adults a whole weekend.
The potato in foil is a good one I do it also but we bought ours in the park so this is what you do if you don't have a microwave.
Wash potatoes and don't peel it. Pierce holes in the potato.
Next cut piece of foil that will cover the whole potato, place potato in middle of foil and throw salt, black pepper, mixed herbs, fresh garlic (always

) on. Roll potato to cover the whole veggie.
Then close up potato with foil and make sure it's properly closed.
You can then place your foil looking rocks (that's what it looks like to me) in the coals on the side. Wors takes the longest to cook so we used the braai (BBQ) time for the wors as timer for the potatoes.
When ready open foil carefully, the skin should be black but soft inside and cooked. You can either scoop the inside out or eat it straight out of the skin with some butter, salt and pepper.
Hmmm...to hungry now again will have to make it in two weekends time again...and will bring some more ideas
