This crumble has raspberries, blackberries and blueberries but you could use just one variety of berry and it'll still taste good.
Just baked this crumble. I used frozen winter fruit and berries. It was very tasty but the crumble was very thick and not crumbly. I will make again but will use 300g of butter and not 350g. I had to add more porridge oats to give the right consistency. The family enjoyed it though. - 03 Oct 2014
i've made lots of mixed-fruit crisps over the years, and tried this recipe because of the new and interesting way to layer the fruit between crisp on the bottom and crisp sprinkled on top. a great idea, and it really mixed the flavors throughout. a couple of changes i made to the recipe, however --- i used a combo of fresh peaches and blueberries because that's what i had on hand. i did not add sugar to the fruit as it says to do in step 2; seemed unnecessary and it worked fine without. also - 1 1/2 cups of butter?!?! insane - i used half of that amount and it still was buttery and crumbly. i'll make it again for sure. - 06 Jul 2004 (Review from Allrecipes US | Canada)
This is now my family's favorite dessert. Sometimes I cut the recipe in half and use a bag of frozen triple berry mix from the grocery store and a 8 x 8 pan. I have not altered the recipe and it is wonderful each time. Also, I have only used the frozen grocery store mix and it turns out great!! - 23 Nov 2005 (Review from Allrecipes US | Canada)
