Kittencal's Juicy, Juicy... Grilled Onion Burgers

• 1 large egg
• 13 cup milk
• 12 cup dry breadcrumbs (seasoned is good to use)
• 2 teaspoons Dijon mustard
• 2 tablespoons Worcestershire sauce
• 1 12 teaspoons fresh ground black pepper (or to taste)
• 1 pinch cayenne pepper (or Tabasco, optional or to taste)
• 2 lbs ground beef
• 2 tablespoons fresh minced garlic (can use more)
• 2 (1 1/4 ounce) packages dry onion soup mix
• 8 tablespoons butter (use firm butter, do not soften)
• seasoning salt (to taste and added on while grilling) (optional)

1. In a bowl whisk the egg with milk until combined.
2. Add in dry breadcrumbs, Dijon mustard, Worcestershire sauce and black pepper; mix to combine, then allow to sit for 10-15 minutes.
3. Add in the cayenne pepper or Tabasco, ground beef, fresh garlic and dry onion soup mix; using clean hands mix lightly to combine.
4. Shape into 8 balls.
5. Make an indentation in each ball then press 1 tablespoon butter deep into the indentation into the middle of the ball (can use a little more butter if desired).
6. Seal the ground beef completely over the butter patty.
7. Flatten into 8 patties then make a slight indentation with your finger in the middle of the patty, this will prevent you burgers from puffing up like meatballs when cooking.
8. Place on a plate; cover and seal with plastic wrap.
9. Refrigerate for a minimum of 8-24 hours.
10. Remove the patties from refrigerator at least 30 minutes before grilling.
