Voices from the kitchen
“We were composting A-grade black truffle shavings every weekend. Sousco turned that into meaningful revenue — and knowing it feeds someone instead of landfill makes the whole brigade feel better about it.”
“Our sourcing team used to spend hours calling distributors for foie gras and heritage beef cuts. Now I check Sousco at 7am and our prep list is done by 8. The quality is extraordinary for what we're paying.”
