Sometimes they have an unpleasant chemical soapy taste and release too much moisture in the pan which prevents a nice golden crust from forming. If you’ve ever tried caramelizing scallops and it never seems to happen, this chemical could be the culprit.

How do you thaw frozen scallops?
There are two methods to use to defrost scallops without negatively impacting their texture. 1) Defrost them overnight in a single layer on a plate covered with plastic wrap in the refrigerator for at least 24 hours. 2) Place scallops in a resealable plastic bag, air removed and using a bowl, run cool water over them until defrosted, this could take about 30 minutes per pound.

How do you know when seared scallops are fully cooked?
Scallops are very lean, so they cook within minutes in hot oil and on high temperatures. They should have a golden crust and the interior should be opaque in color. The texture should be firm, yet easy to cut through with a fork or knife with little resistance.
