There are a number of clone recipes on that popular recipe site I am not allowed to link to. Google searching 'Soul Custardy Recipe' should get you started. I am going to try adapting the v3 version I found to use Real Flavor's Super Concentrates. I don't have everything I want for it yet so I will have to replace bavarian cream with regular cream and butterscotch with butter toffee until I place my next RF SC order.
