Definition of "gastronomical"

The powers of the Canadian voyageurs and hunters in the consumption of meat strike the greenhorn with wonder and astonishment; and are only equalled by the gastronomical capabilities exhibited by Indian dogs, both following the same plan in their epicurean gorgings.

1847, George Frederick Augustus Ruxton, Adventures in Mexico and the Rocky Mountains, page 267

Do you agree that a bologna sandwich is a satisfactory meal, whereas caviar and champagne, roast duck and baked Alaska, that might be considered a delightful meal? We object, these gastronomical comments are irrelevant to these proceedings, your Honor.
