Tips, Tricks & Variations
For those feeling adventurous or facing a dearth of cream, replace the heavy cream with an equal part of sour cream or plain Greek yogurt for a tangier twist. And yes, low-fat milk will work, although the richness will lightly tiptoe backwards. If pecans aren’t your jam, swap in walnuts or skip the nuts altogether for a smoother bite.
