Here's the Gurobi code to solve the optimization problem:

```python
from gurobipy import Model, GRB, quicksum

# Create a new model
m = Model("optimization_problem")

# Create variables
hot_dogs = m.addVar(vtype=GRB.INTEGER, name="hot_dogs")
cantaloupes = m.addVar(vtype=GRB.CONTINUOUS, name="cantaloupes")
cornichons = m.addVar(vtype=GRB.INTEGER, name="cornichons")
fruit_salads = m.addVar(vtype=GRB.INTEGER, name="fruit_salads")
ravioli = m.addVar(vtype=GRB.CONTINUOUS, name="ravioli")

# Set objective function
m.setObjective(
    6.2 * hot_dogs**2
    + 7.63 * hot_dogs * cantaloupes
    + 9.51 * hot_dogs * ravioli
    + 2.02 * cantaloupes**2
    + 2.71 * cantaloupes * cornichons
    + 5.94 * cantaloupes * fruit_salads
    + 7.99 * cantaloupes * ravioli
    + 9.86 * cornichons**2
    + 2.98 * cornichons * fruit_salads
    + 4.51 * fruit_salads**2
    + 1.45 * hot_dogs
    + 2.82 * cantaloupes
    + 1.43 * cornichons
    + 6.2 * fruit_salads
    + 7.91 * ravioli,
    GRB.MAXIMIZE,
)
