To a large mixing bowl, add the cheese, nuts, mayo, onion, and pepper. Use a rubber spatula to combine all the ingredients until evenly combined.
Line a bundt pan with plastic wrap. Spoon the cheese mixture into the pan, and spread so the top is even. It will fill the bottom of the pan in a shallow layer.
Chill the chees ring for at least 4 hours to overnight.
When you're ready to serve, gently lift the cheese ring from the pan using the plastic wrap to lift. Place a serving platter over the top and invert the ring onto the plate. Peel away the plastic wrap.
Put the jam in a small bowl and place the bowl in the center of the ring. (Or spoon the jam directly into the center of the ring.) Serve with Ritz crackers to spread the dip on. Top with jam and enjoy!
Notes
I did a mix of fine and roughly chopped nuts for some variety, which was a nice little crunch occasionally. I used ¼ cup each pecans, peanuts, and cashews. I used all unsalted nuts since I figured the cheese was salty enough.
It's best to grate the cheese from a block vs pre-shredded. If you let the shredded cheese sit out for 20 minutes, it'll soften a little and be easier to mix and form.
Strawberry or raspberry jam both work great for this recipe.
If you want a kick, try serving with pepper jelly or add a little cayenne pepper to the cheese mixture.
