Buchmann Bakery & Restaurant Supply Distributor in Lakeside distributes over 1,300 wholesale bakery ingredients and food service products from its Moreno Avenue warehouse, operating as a division of Buchmann Egg Incorporated across four Southern California counties. The distribution network supplies bakeries, donut shops, cafes, hotels, and casinos throughout San Diego, Imperial, Riverside, and Los Angeles counties, stocking the same type of bulk egg and flour inventory that fuels production at Mary's Donuts & Coffee on Maine Avenue. Product lines include General Mills flours, Pillsbury mixes, Dawn Foods baking ingredients, Chino Valley Farm fresh eggs, Whalen packaging, and a frozen dessert catalog covering cheesecakes, cookies, brownies, and pies for restaurant and catering resale. The original egg ranch on the Moreno Avenue property transformed into renovated warehouse space with temperature-controlled coolers and freezers, though a retail egg store remains on-site for public walk-in and will-call purchases. That farm-to-distributor lineage parallels the direct-sourcing model at Hillikers Ranch on El Nopal, where another Lakeside operation built a wholesale business around a single agricultural product. The delivery fleet covers four-county routes on a scheduled basis, with will-call service available six days per week from the Moreno Avenue loading dock for same-day pickup of eggs, liquid egg products, cake drums, cake boxes, and specialty baking ingredients.
