First time I made a berry galette. Fruit was runny/soupy. Used puff pastry sheet and baked at 425 x 25 mins. per recipe. Could barely cut the bottom crust with a fork. Not burnt or hard, more rubbery. For fruit/filling issue is just some more cornstarch the answer? For the bottom, should I follow the other recipe that called for 375 oven for 40 minutes?
