Personally I blame the microwave for my abstinence. My parents bought me one when I moved into my own place, aged 24, worried that I was going to starve. But the purchase of a new Bosch oven with a timer that actually works (the old one had one that didn't) has brought me back to the joys of 'proper' baked potatoes. Today I will set the timer to come on whilst I am out on the school run, timing it to end about quarter of an hour before planned tea time, giving the spuds time to cool to child friendly temperature and me to make a tuna mayonnaise filling.
In the hope that I can tempt you to try this nutty, warming delicacy, I paraphrase the instructions for Jacket Potatoes from my trusty Basic Cookery from Good Housekeeping, again given to me by my mum fearing I would starve in my first year in student digs. Preheat oven to 200C. Wash and dry as many medium sized potatoes as required. Prick all over with a fork and place on shelf in the middle of the oven. Cook for 1-1.25 hours.
If using the oven timer, don't worry about not preheating the oven. Just set the the oven to be on for 1.15 hours if you expect to be back close to the end of the cooking time. If you might not be back on time, set the timer for an hour, and the hot oven should continue to cook the potatoes and keep them warm until you get home.
The list of possible toppings is endless. My favourites are; cheese & onion, tuna mayo, bean & sweetcorn in vinaigrette...
