Don't Forget to Poke Use a fork and poke the potato four or five times on each side. These little holes allow steam to escape while the potato is cooking. Forget to poke, and your potato could end up exploding in your microwave from the pent-up steam.
Dry the potato and then pierce it all over with a fork. This allows steam to escape as the potato cooks and will prevent it from exploding in your microwave.
When a potato is cooked in the microwave, the internal water boils and produces steam. Since potatoes have an outer skin, the steam builds up, creating pressure. Eventually, the built up pressure bursts the potato.
A russet potato is usually about 80 percent water, so poking it and trimming off the ends will help the steam escape. Sometimes a potato could be even moister and the water, especially in a larger size potato may be trying to escape as steam from the middle cells of the potato.
Simply take a handful of spuds (four should do the trick depending on how many people you cooking for), place in a microwavable dish, cover and microwave for around 10 minutes on full power.
While these potatoes are marketed as an instruction-friendly convenience to consumers, you can certainly microwave any potato as-is, minus any plastic wrap and requires nothing more than a rinse and skin pierce.
Place the potatoes on a microwave-safe plate and cover them with a damp paper towel or dish towel to keep them moist while they cook. Microwave the potatoes on high. Start with five minutes for one potato and add two minutes to the cook time for every additional potato you're microwaving at once.
As soon as you peel the potatoes, you'll want to place them into a bowl of water so they're fully submerged, and then store the bowl of potatoes and water in the refrigerator. The water will seal off the potatoes from the air, so the chemical reaction can't occur.
Add a tablespoon of butter or margarine to the cooking water when boiling potatoes to prevent the water from boiling over.
Plastic wrap or a paper towel will do the job. Even better is one of these glass domes or $10 plastic covers with vents that allow the waves through to do their thing and still protect against splatter, sputters and explosions.
Anything made of or containing steel, iron, copper or other hard metals should never go in your microwave. Metal surfaces reflect microwaves, which increases the heat inside the appliance and could lead to a fire.
Why potatoes can absorb too much water. If your potatoes have been growing in very dry soil, the potatoes themselves will have a fairly low moisture content when harvested. What this then means is that when the potatoes are build they absorb more water and fall to pieces quite quickly. So annoying!
You can cook potatoes in a microwave without adding any additional water. Just place them in the microwave and get going. This has a great advantage: potatoes don't turn moister than they were to start with. If anything, they'll dry out slightly.
Many microwaves have moisture sensors inside so that all you need to do is press the button that says 'potato' and just wait for the microwave to beep at you. If your microwave doesn't have a potato button, a general rule is that one 7-to-8 ounce Idaho potato takes about 7 minutes to cook. 2 will take about 11 minutes.
For 2 medium-sized potatoes, start with 10-11 minutes microwave time. For 4 potatoes, start with 15-16 minutes in the microwave. When the time is up, get a towel or oven mitt and gently squeeze the sides of the potato. If it gives without resistance and starts to open up, it's ready.
The baking soda bath breaks down the potato's pectin and draws the starch to the surface, which promotes browning and the satisfying crispiness that only a perfectly roasted potato can deliver.
"Baking soda [what Americans call bicarbonate of soda] breaks down the pectin in the potato and draws starch to the surface. What do you get? Wonderful browning and a crispiness you wouldn't otherwise achieve.”
Soaking potatoes in water helps remove excess starch. Excess starch can inhibit the potatoes from cooking evenly as well as creating a gummy or sticky texture on the outside of your potatoes. Cold water is used because hot water would react with the starch activating it, making it harder to separate from the potatoes.
Vinegar causes the potatoes to form a thin crust that further helps in retaining their shape. Vinegar increases the acid pH levels of water which further helps the potato just like when you add a little salt to the water while boiling eggs.
When slicing the potatoes place into water with a little acidity to keep them from turning gray. A small amount of white wine vinegar of lemon will do the trick. Then drain and place the potatoes in foil along with your spices and some olive oil or vegetable oil. Wrap up tight and refrigerate, then grill.
Step 1Wash potato thoroughly and pat completely dry. Pierce 3 to 4 times with a fork. Step 2Place potato on microwave-safe plate and microwave 7 minutes, turning over halfway through cooking. If your potato isn't fork-tender after 7 minutes, continue microwaving in 1 minute increments until fully cooked.
While microwaving to completely cook the potato will result in a soft and mealy Russet, cooking in the microwave for just 5 to 6 minutes before placing in the oven keeps the potato's original texture. Drizzling with olive oil and sprinkling with salt before baking at 400 F will allow the skin to get nice and crisp.
A whole potato or sweet potato can take up to 90 minutes to cook all the way through in a conventional oven; but a potato that's been pre-cooked in the microwave—say for 5 to 10 minutes—only needs about 20 minutes in a 450°F oven to finish roasting.
