Starting a post about this to exchange ideas regarding favorite gluten &/or dairy free products. I have a son who has been eating gluten/dairy free for the last 6-7 years, and I am always looking for new ideas! So list your favorites, or you can list things that you have found really bad, to warn others (this food ain't cheap!!)
Pasta: Tinkyada brand - the closest to real stuff in texture, I find it doesn't overcook as easily as the other brands I have tried
Flours: My current favorites are the pre-mixed blends from Authentic Foods (Gold Bag), but I have had good results from just making a blend from flours bought in the bulk bin too (which is the cheapest way to go). Also, if you have a lot of indian/asian markets where you live (I do) - it is a great source for buying things like rice or sorgum flour cheaply.
Pizza Crust - have never been too ambitious to make my own - the one time I tried, it turned out really bad, but I have had very good luck with the Kinnikinik frozen pizza crusts. Take straight from the freezer, top, and cook.
As a working mom, I rely often on convienence foods. They are also great to send along to school with my son in his thermos, as he prefers a hot lunch. Some of our favorites
Ians: Chicken nuggets, fish sticks and fillets, Chicken patties, Kids meals! (similar to kids cuisine style meals), French bread Pizzas
Amy's: A lot of amy's stuff is gluten free, and more and more is dairy free too. My son enjoys the Thai Stir fry and Noodle stir-fry frozen entrees. He wasn't crazy about the kids meal or pasta bowl (too mushy)
Kinnikinnick: In addition to great pizza crusts, they have great muffins, breads for sandwiches or toast or french toast (our favorite is the white sandwich bread), english muffins (which double as hamburger buns, they make a hamburger bun as well, but we prefer the english muffin, as it is sturdier.) I can do a good quick bread, but my attempts at making yeast bread have fallen short, and I just often don't have the time. We have two local bakeries that I also will buy gluten free bread at, but I find the Kinnikinnick to be just as good. Also, if you can't get this brand near you, they have a website and shipping (I have shipped both to MN and FL) is a flat $10.00, no matter what you order, which is a great deal!! They also have good mixes, and cookies (Montana's Choc. chips are our fave). Their ALTA line is also completely dairy free.
We are completely dairy free as well, but for those that are not, I hear that Grandma Ferdon's is supposed to be awesome - I have seen their stuff in health food stores in the Minneapolis area, and it all looks really good - breads, bakery items, pie crusts etc. They are out of Wisconsin.
For dairy free, we generally use Pacific Foods or Harmony Farms rice milk (I will sparingly use soy if I feel that the recipie needs a thicker textured milk).
There is no such thing as a good substitue for cheese in my opinion. Having said that, if you can tolerate soy, my son loves the Toffuti cheese and cream cheese (they do use distilled vinegar, but so do we, and so do many celiacs - it is a personal decision) The Follow Your Heart brand cheese is good to him as well, it comes in blocks, so needs to be shredded. These are the best brands I have found in terms of them melting (at least somewhat).
Would love to hear what others use and like! Thanks!
