Despite its speed and versatility , though , there are some thing a microwave ca n’t do .

We tappedSarah Brekke , M.S.,Better Homes & GardensTest Kitchen trade name coach , to walk us through the consumable items that we should never microwave , whether because they pose a safety peril or simply due to the Brobdingnagian impact on quality .

Besides simmering , we swear by steaming and make boiled eggs in the Instant Pot or other pressure cooker .

3. Grapes

We adore them fixed , blended intosmoothies , folded intosweetorsavory salads , by the handful as a collation , and metamorphose into wine . But we do n’t love grapes in the microwave .

The science behind this one is quitecomplex , and seems to be related to the fashion electromagnetic field of study establish up between the grape vine . Whatever the actual reason , we keep grapes out of the microwave and instead wangle them in a skillet or roast them in the oven if we are n’t servingfresh grapesin their raw human body .

5. Frozen Meat

But attempt to cook a man of frosty protein totally in the microwave “ will yield hapless results , ” she says . “ microwave manipulate nutrient from the interior out and to get the center of the meat wangle to a safe temperature will result in the exterior of the meat being problematic , dry , and leathery . ” If you want to fudge a piece of gist that is frozen , our Test Kitchen experts recommend that you thaw it in the refrigerator ( overnight often does the trick ) or feel costless to get thing start with a brusk slip in the microwave , before end the cooking in a frying pan , in the oven , or on the grillwork . If you ’re hoping to manipulate the meat from frozen without thaw , release to yourInstant Pot , Brekke says , “ This is a much honorable shaft for cooking larger pieces of stock-still protein . ”

6. Alcoholic Beverages

A fair amount of bibulous beverages are plan to be enjoyed strong : Hot Toddies , Mulled Wine , Hot Buttered Rum , Spiked Hot Chocolate , to name a few .
