Vanilla is mainly for flavoring desserts and for making excellent creams. The aroma is given by the presence of vanillin with antioxidant properties which helps maintain a young organism by counteracting the action of free radicals. It is also useful for fighting stress and defeating insomnia.
For extreme heat, try the Carolina Reaper, a fiery delight from South Carolina. It is a new hybrid of the Capsicum Chinense family, obtained by crossing two species of strongly spicy chili peppers, the Pakistani Naga Morich and a Red Habanero. One of the strongest chili peppers in terms of heat, to be carefully sipped for an intense and rather strong flavor in your dishes.
