He and fellow purveyor Edward sell freshly made pies, quiches, breads and cakes, all made on the site of their shop in Brixton Market. They even make fresh pasta on the weekend - including stuffed tortellini (if you get to the market before they sell out).
Their pastry is excellent. I got to feel some of the sweet pastry before it had been cooked - I have no idea how he got it to be that smooth (and it's a secret!).

I recommend following them on facebook, as you will get all the updates about what they are making the next day, for example today - "Baby Victoria sponges, chocolate eclairs, raspberry, cherry and ginger cupcakes and rhubarb pies are on tomorrow. We'll also have the usual pies, fresh pasta, bakewells, fruit loaf, brownies, jammie dodgers and our lovely golden bread." They had valentines cakes as well. And, what's this I see, fresh bagels?
Even though the cafe is next to a fish stall, and it can be a bit chilly (this is in February), Brixton market is an interesting eclectic mix of stalls and shops - well worth a snoop around. They also sell a range of GF foods in the shop section; breakfast cereals etc, so it's a sort of gluten free one stop shop.
This isn't fancy foodie food, it's great traditional British staples. If it's a bit of gluten free carbohydrate indulgence you are after, make a little pilgrimage my gluten free lovelies, you won't be disappointed.
Verdict: Cakes and Pastries and Pies, Oh my!
