1、准备好食材，老姜一块，红糖一包，桂圆红枣枸杞少许（可以不加）

2、红枣去核，切小丁，桂圆去壳，姜切细丝

3、食材放入锅中，加适量的水，中小火煮15分钟

/iknow-pic.cdn.bcebos.com/10dfa9ec8a1363278aa0c1459c8fa0ec08fac773"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/10dfa9ec8a1363278aa0c1459c8fa0ec08fac773?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/10dfa9ec8a1363278aa0c1459c8fa0ec08fac773"/>

4、红糖放在自己饮用的杯子或碗里，倒入姜枣茶，不需要搅拌即可饮用，这样头几口就能喝出红枣、桂圆、枸杞本来的淡淡甜味，红糖会慢慢化开每一口都比上一口更甜。
