This isn't quite exact, but 1/4 cup of butter (so a half stick if you're in the US) is 57 grams according to the conversion chart from allrecipes below. So use just a slightly heavy 1/4 cup or 1/2 stick.
Yellowtail, including Yellowtail Jack (Seriol landei), are recognized by a yellow stripe across their body and their yellow tail. Range & Habitat: Yellowtail is caught year round, but more commonly during summer in the Pacific Coast and the Sea of Cortez. They are caught primarily with hook and line, and their average weight is 10 to 20 lbs.
The cottontails that live in and around White Sands National Monument are desert cottontails (also called Audubonâs cottontails; Sylvilagus audobonii). They look like typical rabbits, with long ears, grey-brown fur, and large feet. Desert cottontails also typically have an orange colored throat patch. They are about 14-15 inches long (35.5-38 cm) and weigh around one to two pounds (450-900 grams), making them much smaller than the jackrabbits also found here at White Sands.
