Just tried the Patsypie crumble crust this past weekend. It's like the Keebler crust I used to buy, except it's gluten free. In other words, you don't have to bake it and it doesn't come frozen. It's ready to go. I filled it with chocolate pudding, topped it with whipped cream and the result was an amazing chocolate cream pie. It took all of ten minutes. Best part was, our friends who came for dinner thought I was eating gluten again. They asked for the recipe for the crust. You can find it at www.patsypie.com. I've been buying their peanut butter cookies and brownies for years. I think Patsypie has some of the best gluten free baked stuff out there. Anyhow, if you're looking for a gluten free crumble crust, this one is worth a try.
I've mentioned Montreal's Patsypie bakery before. I still think it's the best around and, believe me, I must have tried just about every company out there. I recently tried their new pie crust. It's like a Graham cracker crust, but gluten-free. It's one of those fill and serve type crusts, like Keebler makes. We made a chocolate cream pie with it. Our friends were asking for the recipe. It's amazing. They've also got some new muffins and brownies, but haven't had the chance to try either yet. The the thing is, any Patsypie product I've tried so far has been excellent. It's the only gluten-free stuff i can bring home that my wife will eat also.
By far the best baked gluten-free In Montreal comes from Patsypie (http://www.patsypie.com/) as mentioned by plateauman. But I don't think the bakery is open to the public. They make cookies, biscotti, brownies and muffins. I buy from HealthTree on the west Island, but I've seen their products in other stores too, even Metro. I highly recommend their brownies, peanut butter cookies and cranberry biscotti.
As for restaurants, I find that most in Montreal now understand gluten-free. While these don't have an exclusively gluten-free menu, they are all safe bets:
Portuguese: Braseiro, 8261, boul. St-Laurent corner Guizot, 514.389.0606. very reasonable and consistenly excellent. Try Marco's Chicken plate!
Latin American: La Caretta, 350 Rue Saint Zotique East (514) 273-8884. Lots of corn options. Great corn tamales. Wonderful pupusas. It's very casual and not fancy, but VERY tasty and fun.
Italian: Ottavio, 1134 Marcel-Laurin, Ville-St-Laurent, Qc (514) 335-7966. They actually have a gluten-free menu. While it's not the best Italian you'll ever eat, they do offer several gluten-free options and are very careful about it, even providing separate, wrapped knives and forks.
For chocolate lovers and crepe lovers: Juliette et Chocolat (http://www.julietteetchocolat.com/che...) is great bet. They offer over 40 different types of hot chocolate plus some excellent and gluten-free buckwheat crepes.
You can also get buckwheat crepes at several other Montreal restaurants. Just make sure to ask if they mix in any wheat flour. Most don't, but some do.
As I said, most Montreal restaurants will attend to your gluten-free needs. Just make clear as to what you can and can't eat.
