With a view to saving energy costs I also use the microwave more. Although it is very energy greedy the cooking time us much shorter.
However, I’ve been experimenting with shorter cooking times on the hob too and have found the following works well. For boiled potatoes cut them quite small, bring to the boil then turn off the hob and leave them in a tightly lidded pan for at least half an hour.
For pasta, first soak in a pan if cold water for several hours, drain. Bring a pan if salted water to the boil, add the drained pasta, return to the boil then turn off the heat and keep tightly lidded, again for about half an hour. Depending on the amount if pasta and what shape you might have to experiment a bit but I found this worked perfectly for the pasta tubes.( mind gone blank on the name)
Washed towels in the sun and now like sandpaper.
