The sauce gets its striking colour from hibiscus flowers and is made with high-quality white Thai chillies grown in northern Thailand. Libby Andrews, marketing director at Pho, said: “Not only does the new SABZU Pink Sriracha look amazing, it is delicious and so fun for summer. Customers who wear pink clothing to any Pho restaurant on a Wednesday can enjoy a spicy pink margarita and select dishes for just £5 each. Our partnership with Pho marks an exciting milestone for SABZU as we introduce the world's first-ever Pink Sriracha sauce exclusively across the UK. "We believe Pink Sriracha perfectly captures today's appetite for bold, playful flavours while staying true to authentic Thai ingredients, and we are proud to bring this exclusive collaboration to life with one of the UK's most loved Vietnamese restaurant brands."
