Ingredients :

• Thousand Island Dressing — The creamy and slightly sweet base that holds everything together. Choose a version with visible pickle pieces in the ingredient list. You can also make it yourself in five minutes: mayo, ketchup, finely chopped pickles, and a touch of mustard.
• Sauerkraut — Drain it really, really well. If you skip this step, the dip becomes watery while baking and the cheese won’t set. Squeeze it in your hands over the sink — you’ll see how much liquid comes out.
• Swiss Cheese — Grate it yourself rather than buying pre-shredded. Pre-shredded cheese is coated in starch to prevent sticking, which stops it from melting properly. Two minutes of grating yields an incomparable result.
• Corned Beef — The best is the one sliced at the deli counter, then diced at home. Canned works too, but the texture is softer. Cut it into irregular chunks rather than uniform strips.
