In a medium bowl, combine the berries with the honey and cornstarch Mash together slightly with a fork just to release a little berry juice and combine with the cornstarch. Divide the berry mixture between 4 shallow (12-ounce) oven-safe dishes and reserve.
In the bowl of a food processor add the flour, sugar, nutmeg, salt, and lemon zest and pulse to combine. Add the butter and pulse until the butter and flour are just barely combined, about 15 seconds. Transfer the butter mixture to a bowl and toss with the sliced almonds. Evenly divide the topping between the 4 dishes by sprinkling it over the berries to almost cover completely. Transfer to the oven and bake for about 20 minutes or until the top is lightly browned. Remove from the oven and serve warm with a scoop of ice cream.
