准备

做凝乳

• 将柠檬酸溶解在½杯冷却的泉水中。将牛奶倒入一个不锈钢锅中，静置15分钟。搅拌时加入柠檬酸溶液。用中火将牛奶加热至88°F至90°F，经常搅拌。
• Just before using, crush the rennet tablet and dissolve in 1/4 cup cool spring water. Remove the milk from the heat, add the rennet solution, and stir lightly twice. Let the milk sit for 12 minutes. At this time, the curd (solids) should be pulling away from the whey (liquids). The curd will resemble silken tofu. With a long sharp knife, cut it into 1-inch cubes without removing it from the pot.
• 将锅返回中低温，并不断搅拌凝乳，直到温度达到105°F，约5分钟。
• Place a colander in the sink, and spoon the cooked curds into the colander. (If you want to save the whey, strain the curds over large bowl.) Strain the curds well.

使Stracciatella填充

• 将四分之一的凝结物移到一个小碗中。加入奶油和1/2茶匙。盐，将混合物与手指混合在一起。搁置。将剩余的凝乳转移到一个大碗中。

制作burrata

• Heat a large pot of water (tap water is fine) until it registers 175°F to 180°F on a digital thermometer. Fill a large bowl with ice water and set aside.
• 工作2汤匙。用手指将犹太盐塞入凝乳中。这似乎是很多盐，但不用担心。其中大部分将留在水中。直到它们被浸没在凝固的碗碗中，刚将热水倒入凝乳碗中，而不是直接在凝乳上。静置1至1-1/2分钟。
• 搅拌Stracciatella填充物，如果看起来太干，则添加更多奶油。
• With your hands, gloved or bare (remember, the water is very hot!), gather half of the curds into a ball, lift it from the bowl and let it stretch back into the water. Continue to stretch it until it is shiny and elastic. The curds should immediately and effortlessly stretch. If they don’t, return them to the hot water until they are soft and pliable, and stretch easily. (Tip: if the water has cooled too much, drain it and add more hot water from the pot.)
• Working quickly, gently form the stretched mozzarella into a disk 5 to 6 inches in diameter and about 1/4 inch thick. Place the disk in the palm of your hand. carefully spoon 2 to 3 Tbs. of the stracciatella filling into the center of the mozzarella disk, adding 2 to 3 Tbs. more cream from the bowl. Twist the ball to seal. Place the burrata ball into the ice bath and let it cool until firm, 5 to 6 minutes. Repeat the process with the remaining curds, stretching and filling with the remaining stracciatella filling.
• 立即食用burrata，或将其包裹在保鲜膜中并冷藏，直到准备使用。在48小时内服务。
