Bò lá lốt (bo la lot) is marinated beef wrapped in betel leaves which are then grilled or fried. They sort of look like stuffed vine leaves.
My grandma chews betel leaves as it's quite refreshing. I read here there are many health benefits of eating betel leaves - I'm not sure how much of this is medically proven, nevertheless bò lá lốt is delicious because it's so juicy when cooked. It's my favourite Vietnamese snack/appetizer.
Betel leaves can be purchased from Chinese or Thai supermarkets.
It can be time consuming wrapping the individual betel leaves, so we only make bò lá lốt occasionally.
We've never tried frying the bò lá lốt because it's healthier to oven grill or barbecue them. Also we serve the bò lá lốt with a lettuce salad and a dipping sauce such as nước mắm pha.
