Strain sauce into a bowl; pour into whipping siphon and charge. Shake to combine.
Heat olive oil in a large skillet over medium heat. Add mushrooms; cook and stir until soft and tender, about 5 minutes.
Heat 1/4 cup vinaigrette to just boiling in a separate skillet. Add spinach; cook until just wilted, about 30 seconds. Remove from heat.
Heat grapeseed oil in a large skillet over high heat. Remove scallops from plastic bag; pat dry with a paper towel. Cook until golden brown, 30 to 45 seconds per side.
