Garten’s burger recipe called for 2 pounds of ground beef, 1 tablespoon of Dijon mustard, 3 tablespoons of olive oil, and 1 teaspoon each of salt and pepper.
Normally, I buy inexpensive ground beef, which costs about $4 per pound. But luckily, I found grass-fed ground beef at Walmart for just over $6 per pound, which worked perfectly for this recipe.
Per Garten’s instructions, I also planned to serve the burgers on English muffins and top them with caramelized onions.
So, I gathered halved English muffins, 2 pounds of yellow onions, 2 tablespoons each of olive oil, unsalted butter, and sherry-wine vinegar, half a teaspoon each of pepper and fresh thyme, and 1 teaspoon of salt.
