This recipe uses instant powdered mashed potatoes and exceeds any expectations that you might have when hearing the word "instant". But if you carry a supply of fresh potatoes in you backpack (or car trunk), feel free to prepare mashed potatoes from scratch. Last eaten at a lake somewhere at an unpronounceable lake in Poland, this recipe had to be doubled for two very hungry bikers. Otherwise, the given amounts serve two persons well.
Cut the onion and the apple into small pieces. Heat some/a lot oil or butter in a pan and fry the onions. The more fat, the better the outcome. When the onions are soft, add the apples and continue frying until the onions have reached the desired darkness but the apples are not quite cooked through to the middle. Only very experienced cooks can time this combination optimally. Season with pepper and salt. If you had a hard day, add some more salt.
In another pot, prepare the instant mashed potatoes according to instructions with water or milk. Stir in the apples and onions and add one or more pieces of butter to melt on top of everything. Don’t break the spork while stirring. Enjoy. And don't let your partner steal half your mashed potatoes just because (s)he is the quicker eater!
