Model Bakery's wood-fired English muffin is the single most famous food product made in Napa city. Developed at the St. Helena bakery (opened 1984 under Karen Mitchell), the muffin uses a long ferment (8-12 hours) and a wood-fired oven to produce a crust that standard English muffins do not achieve. The result is a different texture and flavour profile: chewier interior, crispier crust, more complex fermented flavour from the longer rise. Oprah Winfrey included them in her Favorite Things list in 2014, and the Oxbow location sells vacuum-sealed packages for travel. The muffin with cultured butter and local strawberry jam is the canonical Napa breakfast, available from 06:30 at the Oxbow location.
