For Serving
Preparation
- Step 1
Make the dumplings: In a medium bowl, whisk together the flour, granulated sugar, baking powder, ginger and ½ teaspoon salt. Pour in the cream and stir with a spatula until combined.
- Step 2
Prepare the blackberries: In a 10-inch cast-iron skillet (or other shallow 2-quart dish that is both stovetop- and oven-safe), whisk together the sugar, cornstarch and ¼ teaspoon salt. Whisk in ¼ cup plus 2 tablespoons/90 milliliters water, and then stir in the berries. Cook over medium heat until bubbling and then simmer for about 5 minutes, stirring occasionally.
- Step 3
Portion the dough into about 16 small dumplings (about 1½ tablespoons/28 grams each) and decoratively top the fruit with them. Cover the skillet with a lid, if you have one (or a sheet of aluminum foil, or a heatproof plate wider than the cooking vessel), and cook the dumplings for 15 to 20 minutes, until a wooden skewer inserted in the center of one comes out clean and the tops are dry to the touch. Let sit for about 5 minutes to cool.
- Step 4
To give the dumplings a little optional extra color and texture, prepare an egg wash: Whisk the egg and ¼ teaspoon salt in a small bowl. Brush the dumplings with the wash, sprinkle with turbinado sugar and broil for 1 to 3 minutes, watching closely, until the dumplings are nicely browned.
- Step 5
Serve warm, with a drizzle of heavy cream or a scoop of ice cream, if desired. Fruit slump is best the day it is made, but will keep tightly wrapped in the refrigerator for up to 3 days. Reheat in a 300-degree oven for about 20 minutes.

In Nova Scotia we make this with blueberries and call it a “grunt” because of the sound it makes as the berries reduce and bubble around the dumpling topping. Blueberry grunt is a quintessential summer dessert in this part of the world. Easy and delicious!
Excellent. I used a combination of blackberries and blueberries because I didn’t have enough blackberries on hand. It’s great with vanilla ice cream but very good without it, too.
In Québec, they are called « grands-pères » or grandfathers! And are usually steamed in a maple syrup sauce or with blueberries.
I hate to be that person who reviews a recipe after not following it to the letter, but I'm leaving this for others who may want to avoid the stovetop route. I mixed the berries and added them to a greased 9x13 glass pan. I topped with the dumpling batter and baked at 350 degrees for 30 minutes, then added a milk wash to the dumplings and broiled until brown. The berries thickened well, the dumplings were cooked through, and it was delicious!
I had some blueberries and sour cherries languishing in the freezer, so I used those, with 2/3 c sugar, a squeeze of lemon juice, and 2 Tbs cornstarch, and I thought the sweetness and consistency were perfect. I have celiac, and wasn't sure if gluten free dumplings would turn out, but I braved it anyway, and am happy I did! They were tender and chewy and cooked all the way through. Some homemade vanilla frozen yogurt on top makes it an excellent hot summer evening dessert.
Tried this recipe to disastrously messy but delicious results. I’m not sure if it’s because I used too many blackberries (hard to measure six cups exactly) but it bubbled over onto the cooktop and the resulting mess was a total pain to clean. It was so bad that it looked like a crime scene, with all that red/purple blackberry liquid spilling everywhere! Be warned!
