Yerba mate, also known simply as mate, is an herbal tea made from the leaves of the plant Ilex paraguariensis, which is native to South America. The beverage is prepared by steeping dried leaves in hot water and can also be served cold. Like black or green tea, yerba mate contains caffeine, which can enhance alertness and focus^[2][6].

Traditionally, yerba mate is served in a hollowed-out gourd and sipped through a metal straw known as a bombilla^[4]. It is recognized for its unique beverage experience, providing energy and a smooth boost due to the combined presence of caffeine, theobromine, and polyphenols^[4]. In addition to being popular in South America, yerba mate has gained recognition and consumption in other regions, including the United States and Europe^[6].

While generally safe for most adults when consumed in moderation, excessive intake—around 1 to 2 liters per day—has been linked to an increased cancer risk in some studies, especially when combined with smoking or alcohol^[2]. It is advisable for individuals, particularly those who are pregnant or taking medications, to consult a healthcare provider before consuming yerba mate^[2].

Overall, yerba mate is well-regarded for its stimulating effects and cultural significance, particularly in countries like Argentina, Uruguay, and Paraguay^[1].

Thermal shock in coffee processing refers to a technique that involves exposing coffee beans to dramatic temperature changes during fermentation, which impacts the flavor profile of the coffee. This method is particularly notable for its ability to enhance the extraction of flavors from the coffee cherry.

The thermal shock process typically starts with the selection of ripe coffee cherries, which are then cleaned and prepared for fermentation. The cherries undergo fermentation in a controlled anaerobic environment, where unique yeast strains are added to encourage specific flavor developments. After initial fermentation, the coffee is subjected to a heating phase where it is heated in its juices to temperatures between 104 and 122 degrees Fahrenheit. This heating is intended to expand the pores of the coffee beans, allowing them to absorb the juices' flavors more effectively. Following this, the beans experience rapid cooling, which contracts the pores and locks in the absorbed flavors^[1].

The result of this process is often a coffee that exhibits complex flavors, such as strong floral notes and fruity impressions, making it appealing to those who enjoy tasting the intricacies of coffee beyond traditional profiles^[4]. The careful manipulation of fermentation and thermal shock helps produce a distinctive and vibrant coffee experience^[6].

A canelé is a small French pastry characterized by its rich flavor of rum and vanilla, featuring a soft, custardy interior and a dark, caramelized crust. Typically shaped like a small, striated cylinder, canelés are traditionally associated with the Bordeaux region of France, where they are believed to have originated from the Couvent des Annonciades either in the 15th or 18th century^[1][4].

The pastry is made using a batter that consists of milk, eggs, flour, sugar, and rum, and it is often quite challenging to prepare due to the specific techniques required^[2][5]. To achieve the signature texture, canelés are baked using molds that are traditionally made of cooper and coated with beeswax, which helps create their glossy finish and prevents sticking^[5][6].

Canelés are particularly known for their juxtaposition of a crunchy exterior and a pudding-like, moist center, making them a delightful treat often enjoyed for breakfast, as snacks, or as desserts^[1][5]. Their popularity has led to various adaptations and offerings in pâtisseries both in France and abroad^[1].
