    Recipe Tips and Tricks

    • Don't boil the cheese sauce! High heat can cause the cheese to separate and become grainy. Keep the sauce at a gentle simmer over low heat.
    • When purchasing the pastrami, ask for it to be shaved. Then, before using the pastrami, give it a quick chop with a large kitchen knife.
