This three-element pattern works well for taller cups, such as takeaway paper cups that have a narrow diameter. The pattern requires a high flow rate, and it draws largely upon the pushing technique. Up until the 9-second mark, the heart-in-a-heart pattern mirrors the tulip design. At this point, to facilitate the eddy flow you use the highest flow rate in the Latte Art Lexicon — between 30–40 ml/sec — leading us to use the term turbo to describe this manoeuvre. If you are not confident with the high flow rate, you won’t manage to fully encapsulate the second heart inside the first. Experienced latte artists apply this technique as an added element to advanced designs; e.g., the tulip can look great with a heart-in-a-heart at the top.
Over-aerated milk will lack the elasticity to perform well with this design because the eddy current depends on the high liquid content of the foam in order to flow quickly. The heart-in-a-heart pattern depends on letting only a minimal amount of time elapse between steaming the milk and pouring it, in order to avoid unwanted drainage.
