Introduction
The BLT is an American classic, but the Southern BLT elevates it to new heights. In the South, this isn’t just a sandwich—it’s a summer tradition. The key differences? Thick-cut, often peppered bacon; ripe, juicy tomatoes straight from the garden; and a generous slather of Duke’s mayonnaise (a Southern cult favorite). Served on soft white bread, often toasted, it’s the perfect balance of salty, creamy, crunchy, and acidic. This recipe honors that legacy while giving you room to make it your own.

Instructions (Step-by-Step)
1. Cook the bacon
In a large cast-iron skillet over medium heat, cook bacon until crispy but not brittle (about 6–8 minutes). Drain on paper towels. Southern tip: Reserve 1 tbsp of bacon grease.
2. Prep the produce
Slice tomatoes ¼-inch thick. Lay on paper towels, sprinkle lightly with salt and pepper (draws out excess moisture). Pat dry after 5 minutes. Wash and dry lettuce leaves.
3. Toast the bread
Spread a thin layer of reserved bacon grease in the skillet (or use butter). Toast bread slices until golden brown on one side only (for soft interior crunch).
4. Assemble
Spread 1 tbsp mayonnaise on the untoasted side of each bread slice. On bottom slices, layer: lettuce → 2 slices bacon → tomato slices → second slice of bacon. Top with remaining bread, mayo-side down.
5. Slice & serve
Cut diagonally (never straight—Southern rule). Serve immediately.

History of the BLT
The BLT evolved from tea sandwiches in the late 1800s, but its modern form appeared after WWII when fresh lettuce and tomatoes became widely available year-round. The Southern version took hold in the 1950s as home gardeners grew beefsteak tomatoes. Southern cooks replaced delicate bread with soft white sandwich bread and insisted on thick-cut bacon for “chew.” Mayonnaise, especially Duke’s (created in Greenville, SC, in 1917), became non-negotiable. Today, the Southern BLT is a symbol of summer, often served with sweet tea or a cold glass of buttermilk.

· Uses seasonal produce – Encourages eating fresh, local tomatoes.

Formation (How to Build for Best Structure)
1. Base layer – Toasted bread, mayo-side up (prevents soggy bread from tomato juices).
2. Lettuce – Acts as a moisture barrier.
3. Bacon – Place 2 slices side-by-side, slightly overlapping.
4. Tomatoes – Single layer, no overlapping (prevents sliding).
5. Top bacon – Crosswise to bottom bacon for structural integrity.
6. Top bread – Mayo-side down.
Pro method: Press gently, then secure with a toothpick through the center before slicing.
