More judaico refers to the Jewish tradition of adding extra precautions and restrictions to certain laws to ensure that they are followed properly. Think of it like extra steps to make sure your food is cooked safely or your toys are put away properly after playing with them.
For example, the Jewish law says not to work on the Sabbath, but the concept of more judaico would mean going the extra mile to make sure you don't even come close to breaking the law. This could mean not driving, not using electronic devices, and refraining from certain activities even if they are technically allowed.
Another example is the kosher dietary laws. The more judaico approach would mean taking extra measures to ensure that no non-kosher food comes into contact with kosher food. This could include having separate utensils and plates for meat and dairy, and carefully checking ingredients to make sure they meet kosher standards.
Overall, more judaico is about taking extra precautions and restrictions to uphold Jewish laws and values.
