Baking soda is an effective way to make pork crispy, as it has a high alkalinity content that helps to tenderize the meat and give it a delicious crunch. It also adds a subtle flavor that pairs well with many seasonings and spices. Although some people may prefer using baking powder to achieve a more elevated texture, baking soda can still be used successfully when combined with other ingredients like sugar or oil. Ultimately, the choice of which ingredient to use depends on the desired outcome and individual preferences.
