I've been doing Keto for several months now, but recently I've had a hankering to make Key Lime pie. I've always done the traditional kind (key lime juice, egg yolks, and sweetened condensed milk baked in a graham cracker crust and topped with whipped cream). The fake green Jell-O colored ones aren't worth it. The egg yolks are fine, I can bake it in ramekins and do it crustless, and I figured out a sugar-free whipped cream option, but the sweetened condensed milk has me stumped. Does anyone have a good substitute recommendation for sweetened condensed milk?
