Even a unidirectional laminated wood is stronger than "solid" wood if
properly designed and implemented (with the layers alternated "cup up"
to "cup down") and is also more dimensionaly stable than "solid wood"
as it resists warpage pretty effectively.

But for a pantry shelf (18 x 30 inches) dimensional stability and warping/cupping aren't
a big problem. If you trap the edges in dadoes, warping is nil. If the face of the shelf
is pinned (or hidden by a face frame) the shelf can change depth; who'd notice?
