"Create a keto-style English muffin recipe suitable for breakfast sandwiches. It should be low sugar, high in structure, and sturdy enough to split and toast. Make it quick and easy for a 2-person household, using imperial units. Include a method that works well in a muffin tin or ring mold, and aim for a traditional English muffin texture rather than a biscuit or cake texture. Keep it keto-friendly and appropriate for weight loss and type 2 diabetes management."
