Similar in taste and texture:
* Marie biscuits: These are very common in South Africa and are similar to Rich Tea biscuits in taste and texture. They are often served with tea, and they can also be used in desserts like biscuits and custard.
* Toffee biscuits: These are a bit sweeter than Rich Tea biscuits, but they have a similar crumbly texture. They are often enjoyed with a cup of coffee or tea.
* Rusks: These are hard biscuits, usually made with wheat flour and often flavored with cinnamon or nutmeg. While they aren't as delicate as Rich Tea biscuits, they are a popular snack in South Africa, especially with coffee or tea.
Different, but still popular biscuit options:
* Malva pudding: This is a South African dessert that includes a sticky, sweet, caramel sauce and is often served with custard or ice cream. While it isn't a biscuit, it is a popular sweet treat in South Africa.
* Peanut butter biscuits: These are popular in South Africa and often enjoyed with tea. They are a bit sweeter than Rich Tea biscuits, but they have a similar crumbly texture.
Ultimately, the best "equivalent" would depend on what you are looking for in a biscuit. If you are looking for something similar in taste and texture, Marie biscuits would be the closest match. However, if you are looking for a more South African experience, then Toffee biscuits or Rusks might be a good choice.
