Monday's Tucson Forecast: Another week of warmthMonday's Tucson Forecast: Another week of warmth Monday, April 17 2017 8:12 AM EDT2017-04-17 12:12:21 GMT. TUCSON - April tends to be one of the quieter months of weather in the Old Pueblo. It's certainly living up to the billing this week.
it can bake while you eat the meal. if you bake the apples with the topping ahead of time, the crisp won't be crisp. or make the whole thing the night before, and enjoy it cold. the topping still won't be crunchy because the moisture from the apples will soften it.
I have done that (Apple Crisp is one of my favorites) but my advise is to mix everything up but put the topping on just before you put it in the oven. I keep it in a zip-top bag and just dump it on at the last minute.
