The short answer is – you can. Use the same amount of bottled juice as you would use fresh. Keep in mind that fresh lime juice has a richer aroma than bottled – the bottled juice often tastes tart or muted due to preservatives, and it contains less vitamin C. On the other hand, it’s easier to predict how your cake will turn out if you always use the same brand of bottled juice. It’s simply a matter of preference or the particular recipe you want to try out. Some recipes ask for fresh lime juice, while others are designed to be made with bottled juice. One thing to keep in mind thought is - lime juice does not last long.
