What method can be used to determine the ideal ingredient proportions for a new sandwich?

The ideal method to determine the perfect ingredient proportions for a new sandwich is to conduct tasting panels with varying proportions. This approach involves gathering a group of people who can sample different versions of the sandwich with different ratios of ingredients. By collecting feedback on taste, texture, and overall enjoyment, you can identify which combination resonates best with customers. This empirical evidence is crucial for making informed decisions about the final recipe, ensuring that the sandwich appeals to the target audience.

The other strategies may provide useful insights or information but do not directly evaluate taste preferences. Advertising alone does not influence the quality or taste of the sandwich itself, while relying solely on customer service feedback could yield limited results, as it often involves reactions to existing products rather than exploring new options. Looking at competitor recipes can offer inspiration but might not adequately cater to specific consumer preferences or trends unique to your brand. Therefore, conducting tasting panels stands out as the most effective method to determine the desired ingredient proportions.
