For the roasted garlic spread: Combine the oil and garlic in a small saucepot, turn the heat on to low and let sit until the garlic floats, about 30 minutes. Remove from the heat and let cool.
Remove the garlic from the oil and place in a small bowl. Add 1/4 cup of the cooked olive oil and a pinch of salt to the bowl and mash with a fork until coarsely mixed. Reserve the remaining oil for other uses (including griddling the Texas toast).
For the ricotta: Combine the milk and buttermilk in a heavy saucepot, turn the heat on to medium-low. Stirring very occasionally, check the temperature until the mixture reaches 180 degrees F. (If you do not have a thermometer, watch for curds to begin forming, turn the heat to low and cook for another 5 minutes.)
Remove the pot from the heat and let the mixture sit for 1 hour to let the curds fully develop. Do not stir the mixture during this time.
Line a colander or other large strainer with cheesecloth and set over a large bowl. Gently ladle or pour the mixture over the cheesecloth. Allow the whey to drain from the curds and collect in the bowl below. (Whey can be saved for other uses, mostly anything buttermilk can be used for). After about 1 hour of draining, transfer the curds to a small bowl and season with salt. (If a creamier consistency is preferred, a few tablespoons of cream can be added to the ricotta to loosen it)
For the Texas toast: Heat a heavy skillet or pan over medium-low heat for a few minutes. Add 2 tablespoons of reserved roasted garlic olive oil to the skillet, then add a slice of bread. When the one side has reached a deep golden brown color, remove the slice from the skillet. Add 2 more tablespoons of oil to the skillet and proceed to griddle the other side of bread. When it has reached a deep golden brown, remove from the skillet and sprinkle with salt. Repeat with remaining slices.
Slice the tomatoes into thick slices and sprinkle with salt.
Smear the Texas toast with 2 tablespoons roasted garlic spread. Assemble tomato slices on top of a slice of toast (1 tomato per slice). Place several small dollops of ricotta on top of the tomatoes. Top with basil. Sprinkle with more salt and a twist of freshly ground black pepper. Eat.
