What is a key factor in achieving consistency in sandwich quality?

Achieving consistency in sandwich quality primarily hinges on maintaining accurate ingredient proportions. This practice ensures that each sandwich is constructed with the same ratios of ingredients, which directly influences taste, texture, and overall customer experience. When the proportions are precise, customers can expect the same delicious sandwich every time they order, fostering trust and loyalty in the brand.

While variability in ingredient sourcing can introduce inconsistency, using only one ingredient supplier may not guarantee quality across all aspects and could limit variety. Allowing chefs to freestyle recipes could lead to a lack of standardization, making it difficult to guarantee the same flavor profile or quality each time. Therefore, focused attention on precise ingredient proportions is crucial for delivering the high-quality sandwiches that customers expect consistently.
