Summary: I have all 3 sizes; I really only use the medium
Comment: I first had the medium size of the OXO Good Grips cookie scoop, and I love it to pieces. I've had it a couple of years, and leave it soaking in a mixing bowl of water all the time, and wash it in the dishwasher, top rack.... it looks brand new. I use it at least once a week. It's nice not to have to use 2 teaspoons to scoop dough and try and figure out if all the cookies are the same size. The cookies are also perfectly round and professional looking. I scoop dough with the scoop, and scrape off excess to level the dough against the side of the mixing bowl.
But then I thought, wouldn't it be great to make jumbo cookies and not have to scoop so many times? And wouldn't it also be great to make small cookies, so when I made a batch to take to work, there's technically more cookies to go around per batch?
I think the large and small cookies scoops were unnecessary. Here's why:
The small scoop: One of my favorite cookies to make is oatmeal chocolate chip cookies. The small scoop is hard to use with cookie dough that has chocolate chips or nuts in them, I feel, because it's too small for those additions to a dough. And if a dough has both nuts and chips in them, like a macadamia nut & white chocolate cookie, or chocolate chip & walnut/pecan cookie, forget about it. It's too difficult to get the dough/chip/nut ratio right in each cookie. I do like this small scoop for my peanut butter oatmeal sandwich cookies; they have a peanut butter creme filling, and they're very rich, so it's good to have a smaller cookie size for these. Unfortunately, the PB oatmeal & creme filling cookies aren't asked for very often in my family. Okay, I'll admit, they're never asked for, so I've only made them twice.
The large scoop: I do like this size for my oatmeal chocolate chip cookies, but I don't like it *that* much better than my medium scoop size. And I don't like this scoop for my peanut butter blossom cookies (peanut butter cookie rolled in sugar, and when they come out of the oven, a Hershey Kiss is placed in the center of each cookie to melt).... with such a large, rich cookie, I swear the large size of this cookie doesn't taste as peanut-buttery. When I mentioned this to my family as we ate them after dinner, my brother told me I wasn't crazy, it's the same recipe, but it doesn't taste as much like a peanut butter cookie. The large scoop is simply too big for this cookie, or any other rich cookie.
The medium cookie scoop is the best of both worlds, it's the cookie scoop you should get if you're wondering what size to get. It's a great size for rich cookies, it's a great size for cookies with chips and nuts in them. I feel that the other two scoop sizes are likely to only clutter your kitchen utensil drawer, like they do in mine.
