1. Place verjus, wine, vinegar, peppercorns, thyme, bay leaf, and 2 shallots in a medium saucepan over medium-high heat. Cook, stirring occasionally, until liquid is reduced and thickened, about 20 minutes. Strain into a medium saucepan; place over medium heat. Stir in butter until melted.

2. Reduce heat to low and add crab and chives; season with salt and pepper. Cook until crab is heated through.

3. Meanwhile, fill a high-sided skillet 2 inches high with oil; heat over medium-high heat until oil reaches 300 degrees on a deep-fry thermometer. Place flour in a small bowl; add remaining 2 shallots and toss to coat. Add shallots to hot oil and cook until lightly browned. Transfer to a paper towel-lined plate to drain; season with salt and pepper.

4. Divide grits evenly among small bowls. Top with crab mixture and shallots. Garnish with tobiko and serve.
