mix the berries and 1/4 cup of the sugar in a small non stick cake pan, loaf pan or pie plate. Incorporate 1 teaspoon of the vanilla, 1 teaspoon of cinnamon, half the zest and all the juice of the lemon. Take two tablespoons of the butter and evenly distribute over the berries in little lumps.
In a small mixing bowl, mix the remaining ingredients to a crumbly consistency. I usually mash them with a fork to break up the butter. Sometimes if the butter is too cold to mix well I work through it with my hands. Spread the finished mixture over the berries in the pan.
I tend to shake a dash of cinnamon over the top and sometimes an extra teaspoon of butter broken into little pieces to help brown the top.
Put in the oven. You will start to smell it when it is nearly done. You want a nicely browned top with bubbling dark liquid at the edges. This tends to take 20-30 minutes. Serve hot from the oven in bowls with a scoop of quality vanilla ice cream on top.
