  • "Convivial cooking"
  • Coffee
    • "A Coffee percolator is a type of pot used for complex brewing of coffee by continually cycling the boiling or nearly boiling brew through the grounds using gravity until the required strength is reached. […] coffee brewed with a percolator is susceptible to over-extraction".
    • "Drip brewing, filtered coffee, or pour-over is a method which involves pouring water over roasted, ground coffee beans contained in a filter, creating the beverage called coffee. Water seeps through the ground coffee, absorbing its oils and essences, solely under gravity, then passes through the bottom of the filter. The used coffee grounds are retained in the filter with the liquid falling (dripping) into a collecting vessel such as a carafe or pot. […] Brewing with a paper filter produces clear, light-bodied coffee. While free of sediments, such coffee is lacking in some of coffee's oils and essences."
    • "The moka pot, also known as a macchinetta (literally "small machine"), is a stove-top or electric coffee maker that produces coffee by passing boiling water pressurized by steam through ground coffee. It was patented for the first time in Italy by the inventor Luigi De Ponti for Alfonso Bialetti, in 1933. […] The resultant brew has increased extraction of caffeine and flavours from the grounds versus filter coffee, resulting in a stronger brew than that obtained by drip brewing. […] Moka coffee is not considered to be a true espresso."
