Corn and masa supply chains for LA tortillerías

Based on the provided sources, I can confirm that Masienda is a supplier of heritage (heirloom/criollo) corn that is direct-sourced from Mexican smallholder farmers ^[1][2]. However, the sources do not contain any information about the specific tortillerías mentioned in the question (Tortillería La Mayordomía, Macheen, Kernel of Truth Organics), nor do they provide pricing data for heritage masa versus commodity masa.

• Masienda’s role: Masienda sources heirloom corn varieties directly from small-scale Mexican producers and sells masa, masa harina, and whole corn to restaurants and home cooks ^[1][2]. They describe their corn as “heirloom” or “criollo” varieties, distinct from commodity yellow #2 corn ^[2].
• No data on specific LA tortillerías: The sources do not mention which Los Angeles tortillerías use Masienda’s heritage corn versus commodity corn. To answer that, one would need direct information from those businesses or a survey of their supply chains.
• No pricing information: The sources contain no pricing data for a kilo of heritage masa or commodity masa. Pricing would need to be obtained from retailers, distributors, or market reports.

Open questions requiring additional sources: 1. Which specific LA tortillerías (including La Mayordomía, Macheen, Kernel of Truth Organics) source from Masienda or other heritage corn suppliers? 2. What is the current retail or wholesale price per kilo for heritage masa vs. commodity masa in Los Angeles? 3. What are the specific criollo corn varieties used by each tortillería?
