All of Anyday’s recipes are tested (and retested!) in many different microwaves and home kitchens to make sure they work — and work well.

Select your microwave wattage in the dropdown. The cook times in this recipe will automatically change accordingly.

To find your microwave’s wattage, look at the front panel, the side of the door, in the back, in the user manual, or Google the model number. If both an input and output wattage are listed, use the output.

Wattage translates to how powerful the microwave is. The higher the wattage, the faster your food will cook. The lower the wattage, the longer the cook time.

When in doubt, start with less time — you can always add more.

to make Sunday morning biscuits


  • 2 tablespoons unsalted butter

  • 2 sage leaves
  • 3 tablespoons all purpose flour, or cornstarch
  • cups (350ml) stock (beef, chicken, or vegetable)
  • ½ teaspoon black pepper

  2. Add the shallots, mushrooms, and sage and cook in the microwave for 4-5 minutes.
  3. Add the remaining ingredients and continue cooking for 5-6 minutes, stirring halfway to prevent overflowing.
  4. Whisk the thickened gravy. If needed, continue cooking until it thickens to your liking in 30-second intervals. NOTE: The gravy will continue to thicken as it cools.
  5. Season to taste with salt and pepper. Allow the gravy to cool and use as desired.
