I went to the Shake Shack site while writing the post on the concretes and was pleasantly surprised to see the October custard calendar already up!
We are really excited about this month's flavors which means we're going to have to go to the gym and/or do some other form of exercise regularly. We love fall flavors and this lineup looks good. We've had Shackenstein, coconut caramel and pumpkin pie before (and maybe s'mores and fluffernutter, but we're not sure about those), and I think they were good (although, since we were at the start of the custard challenge, we were a little generous on the pumpkin pie numerical ratings). We are really excited for ginger pear and apple spice cake. I think I am excited for any custard with the word "cake" in the flavor name. Can't wait to try those out!
