Not Kosher for Passover
Not kosher. The term "banana+shake'" includes a URL-encoded character ('), which represents an apostrophe. During Passover, many Jewish communities avoid foods and items that are considered "kitniyot" (legumes and some other foods) and also follow strict rules about processed foods. The inclusion of a URL-encoded character suggests a processed or digital context, which would not be considered kosher for Passover without specific certification. Additionally, a banana shake itself would need kosher certification to ensure no non-kosher ingredients or equipment were used in its preparation.
