"Falling in love is like eating mushrooms: you never know if it's the real thing until it's too late."
-Bill Balance, Radio personality

The refrigerator light goes on...

It simply doesn’t get easier than this to make dinner. Put the mushroom in the oven with some barbecue sauce on it, turn, turn, serve.

I’ve had a lot of Portobello mushroom “burgers” at restaurants here and there. They’re good, and even though mushrooms are one of the pure umami flavors, there’s always seemed to be something missing. Credit to my wife for suggesting the barbecue sauce. It adds just the right touch.

If you are watching your sodium there are low-sodium barbecue sauces on the market. I have also been seeing more and more bottled sauces that are not made with high fructose corn syrup. While these do use sugar instead, it’s not a lot, and two tablespoons is only about 50 calories.


There are two main categories of onion: green onions and dry onions. Both types are the underground bulb of a plant related to the lily.

Dry onions include yellow (sometimes called Spanish onions), white, and red onions. Choose firm onions with no green sprouts and no soft spots or darkening of the skin.

There are two types of dry onions: those harvested during spring and summer have a higher moisture content and are known as "fresh onions." They have thin, light skins and are milder. Because of the amount of moisture they don't keep well. Fresh onions are also known as "long-day" onions.

"Storage onions" grow August through May and have a thicker, papery skin and are more pungent. The low moisture means that they will keep well. Onions grown in the winter may be labeled "short-day" onions.

There are a number of sweet onion varieties and have traditionally been "fresh onions," but many are now grown year round. Two of the most famous are the Vidalia and the Walla Walla onion. These short-day onions have a very high sugar content - up to 15% - accounting for their milder and sweeter flavor.
