Heat the oven to 425°F, stir the sour cream, mayonnaise, and ranch seasoning together in a small bowl, adjust to taste with the All-Purpose MSG Seasoning, and refrigerate until serving. The dip should look smooth and thick enough to cling to a potato bite.
Arrange the frozen tots across a large sheet pan with space between them and bake for 20 to 25 minutes, or follow the package directions, turning halfway through. Look for golden-brown surfaces and a firm, crisp crust rather than pale, soft sides.
Cook the bacon in a skillet until crisp, drain it on a paper towel-lined plate, and chop it after cooling. The pieces should be small enough to settle into the cheese instead of balancing on top.
Rest the baked tots for a couple of minutes, thread four through their centers onto each short skewer, rotate them into a flat row, and arrange the sticks nearly touching on the sheet pan. The aligned tots should rest steadily without rolling, creating a close-set surface for the cheese.
Distribute the shredded cheese over the rows, add the bacon now for extra crispness or reserve it for finishing, and broil on HIGH for 2 to 3 minutes. Remove the pan when the cheese has melted, watching closely so it doesn’t scorch.
Move the skewers onto a platter and finish with any reserved bacon, green onion or chives, and the chilled dip alongside. Serve while the cheese is soft and the potato edges still have their crunch.
