Looking for a buttery pear? Part of finding good pears is to know the meaning of words eg. beurre (which means buttery) . The literal definition is a pear with the “meat soft and melting; – used with a distinguishing word; as, Beurre d’Anjou; Beurre Clairgeau” That means Beurré Bosc, Beurré Capiaumont, Beurre Hardy, Beurré d’Arenberg, Beurré Duval, Beurré superfin are all buttery tasting pears. Another thing I did when trying to track these buttery pears down is went to the ARS grin catalog https://www.ars-grin.gov/cor/catalogs/pyrcult.html and searched by beurre which yielded these results

Even the USDA has a partial list so I checked google books Scott's Orchardist: Or Catalogue of Fruits Cultivated at Merriott, Somerset - John Scott (agriculturist.) - Google Books and checked again Beurre - Google Search. There are many remarkable pears out there or that were out there that would be worth growing most people have never heard of.
