I have never eaten Islamic halal food before, so I am curious about its taste!
All the foods you eat, excluding some forbidden foods and drinks, are not halal, such as pork meat, dead animal meat, blood, and animals that are not processed without the name of Allah, and some other poisonous and carnivorous animals, and drink like any kind of alcohol and blood. All the fruits and plant-related foods are halal, all the fishes are halal. So, I think most of the time you are eating the halal foods in terms of ingredients, so taste is the same without any extra things in halal foods. If you want to learn more, you can read some resources or watch some YouTube videos about the criteria to be a halal food.
