There can be a noticeable difference in texture between homemade dairy-free milk and store-bought alternatives when used in this vegan eggnog recipe. Homemade dairy-free milk tends to have a fresher taste and smoother texture since it doesn't contain any additives or preservatives that are often found in store-bought options. The homemade version allows for customization based on personal preferences regarding thickness or creaminess, which can impact the final texture of the eggnog. Store-bought alternatives may vary in consistency depending on brands but might lack the freshness and purity that homemade versions offer.
