-1.5" slices

A "-1.5" slice" appears to be a measurement specification rather than a culinary ingredient. In culinary contexts, slicing measurements (typically expressed in inches or millimeters) refer to the thickness of cuts applied to various ingredients such as vegetables, meats, breads, or cheeses. A 1.5-inch slice would be considered relatively thick—roughly equivalent to 38 millimeters—and is commonly used for items like steaks, bread loaves, root vegetables, or firm cheeses. The negative notation is non-standard and may indicate a typographical error or specialized notation in a particular kitchen system.

Slicing specifications guide knife work and cooking outcomes. Thicker slices like 1.5 inches are typically used for grilling steaks, creating rustic bread slices for toasting or bruschetta, cutting root vegetables for roasting, or portioning firm cheeses for boards. Thicker cuts generally require longer cooking times and are suited to high-heat applications where the exterior can develop color while the interior cooks through. This thickness is less suitable for delicate items requiring quick cooking or fine julienne work.
