In a large bowl stir together the pale ale, salt, water and lemon juice.
Add the scallops, cover and refrigerate for 1 hour.
Remove the scallops from fridge and place on top of a stack of 4-5 paper towels. Add another layer of paper towels and allow to drain and dry for 15 minutes. Sprinkle with pepper on both sides.
Cook the bacon in a pan over medium high heat until cooked through, remove from pan, chop and set aside. Add the shallots to the bacon grease, cook until shallots have softened, about 5 minutes. Add the stout beer, scraping to deglaze the pan. Add the mustard, honey and pepper, whisking to combine. Slowly whisk in the olive oil, stirring until thickened. Remove from heat.
Melt the butter in a skillet over medium high heat until very hot. Add the scallops, flat side down, and allow to cook until a dark golden brown crust forms on the bottom, about 2 minutes. Flip and cook until seared on the opposite side. Remove from pan when a slight hint of translucent pink still remains at the center, don’t over cook.
Trim asparagus, cut into 2 inch pieces. Cook the asparagus in lightly salted boiling water for one minute, drain and allow to dry.
Plate the spinach, top with asparagus, goat cheese, and crumbled bacon, dizzle with dressing, top with scallops.
