Which 3 Mix-ins have a constant recipe and do not change when more mix-ins are added?

The correct answer focuses on the mix-ins that maintain a consistent recipe profile regardless of the number of additional mix-ins. Malt, Bacon, and Coffee are designed to have a stable flavor presence, allowing them to combine well with other ingredients while retaining their original taste characteristics.

Malt provides a sweet, malty flavor that does not overshadow other ingredients, lending a rich depth without drastically altering the overall flavor profile. Bacon contributes a savory, smoky element that enhances various combinations without overwhelming them. Coffee adds a slightly bitter richness that balances sweetness, maintaining its essential flavor quality when paired with other elements.

The other options include mix-ins like Chocolate and Caramel, which can dominate or change the overall taste significantly when combined with other flavors, altering the expected outcomes of the final product. Hence, the consistent nature of Malt, Bacon, and Coffee makes them the correct answer in this context.
