SUPERMARKET SAMPLER: TWO FLAVORFUL WAYS TO QUENCH A THIRST.

Byline: Carolyn Wyman & Bonnie Tandy Leblang

Haagen-Dazs Sorbet - Raspberry Lemonade Swirl, and Margarita. $3.09 per pint.

Bonnie: Like all Haagen-Dazs sorbet, these two new ones are all natural and fat-free. One is a blend of lemonade and raspberry flavors; the other is a bit more unusual combination of lemon and lime juices and a minuscule splash of tequila. Either is a refreshing and low-fat - yet satisfying - way to end a meal.

Carolyn: Haagen-Dazs' latest sorbet flavors were inspired by two popular summer drinks. I'm a big fan of the new flavored lemonades found in the refrigerator case and even more a fan of this raspberry-lemonade frozen version. (The raspberry really zips things up.)

The margarita flavor isn't so much of a stand-alone dessert as a quick and easy way to make frozen margaritas (with or without alcohol). Just put some of this in a food processor along with water, lime juice and optional tequila.

Kellogg's Cocoa Frosted Flakes; $3.19 per 16.1-ounce box.

Bonnie: These Cocoa Frosted Flakes are way too sweet to serve for breakfast. A fiber-less bowl of this cereal won't satisfy a child until lunch, but will instead make him or her hungrier once the sugars have been metabolized.

But served with milk, these could make a good alternative to cookies for an afternoon snack. They contain less fat and fewer calories than cookies, and because Cocoa Frosted Flakes are enriched, more vitamins and minerals.

Carolyn: Frosted Flakes were introduced in 1952 with this one simple but enthusiastic claim, ``Sugar Frosted Flakes are Grr-reat!''

Today, a new chocolate-flavored version of Frosted Flakes (the nutritionally incorrect sugar was excised from the name but not from the food) is being introduced as ``a good source of 10 essential vitamins and minerals,'' ``cholesterol-free,'' ``fat-free'' and approved by the American Heart Association's heart-check certification program.

What I want to know is, is Kellogg's talking about a sugary cereal or a new medicine?

The fact is, none of these boasts are going to impress chocolate lovers, and neither will the Cocoa Frosted Flakes' cocoa taste. It's so weak that you can actually still taste the corn!

Sorry, Tony, but I'm much more cuckoo for Cocoa Puffs.

The Green House Mushrooms - Fresh Enoki Mushrooms, and Dehydrated Portabello, Lobster, and Stir-Fry and Pasta Gourmet Mushroom Blends; $1.49 per 2-ounce package of fresh, or $2.99 to $4.99 per 3/4-ounce package of dehydrated.

Bonnie: I'm always thrilled when we get to review what I call ``real'' food. So, I was very happy when I saw these new mushrooms from the Green House. Mushrooms, after all, are low-calorie, high-fiber vegetables.

First there's the fresh enoki, which will stay fresh for about 10 days. They look like hairpins or long, skinny stalks with tiny white caps. Enjoy them as is in salads, or add them at the last moment to simple soups.

The other four new varieties are all dried and will last in a cool, dry place for a long time. Just rehydrate them in warm liquid for 15 to 20 minutes, then saute and enjoy. Or use them to top a pizza, or to add to a stir-fry or pasta.

The most unusual ones are the lobster mushrooms, so named not because they taste like lobster (they're actually very delicate in flavor) but because they resemble the color of a cooked lobster.

Whichever you try, I think you'll like the convenience of being able to pull them out of your pantry whenever needed.

Carolyn: In my view, cheese and wine varietals are usually much ado about nothing, but that's not the case with mushrooms. The different varieties really are different in taste and texture and also much stronger than the garden-variety supermarket kind. They are truly worth the money, especially in the less perishable, dehydrated forms of most of these from the Green House.

The pasta and stir-fry blends were my favorites, both because of their user-friendly packaging and built-in variety. The fresh enokis look like the little antennae worn by Ray Walston in the old television series ``My Favorite Martian.'' But the mushrooms performed much better in my salad than his antennae ever did as a communications device.
