From the official Angustura website: "Made with the same original secret recipe since 1824, the world famous Angostura aromatic bitters remains the quintessential and definitive ingredient for classic and contemporary cocktails. Its versatility, however, stretches way beyond the bar counter as it serves as a unique flavour enhancer with the ability to marry flavours in the preparation of all food dishes. Angostura aromatic bitters also adds its unmistakable flavour and aroma to 'soft' beverages and desserts."
