I find the best selection for apples is at Farmers' Markets and I always ask the vendor for a recommendation. Tell them what you're making and when you are making it. Ask what apples are good that week because if the apples are coming out of storage they will reflect when they were picked and how they were stored. Jonagold from a market 2 weeks ago may not be as good as this week's. I always get 3 or 4 varieties and cut them up into different sizes depending on how they cook. If you are lucky enough to find a quince grate it and add to your pie.
