Shrove Tuesday, or as its more commonly known Pancake Tuesday is the day before Ash Wednesday and the beginning of Lent. The word Shrove comes from an old word “shrive” which means to confess. On this day people confess their sins and ask for forgiveness.

As Lent is a time of abstinence, Shrove Tuesday is the last day where you can indulge in your favourite treats. Pancakes are associated with this day because it was a way to use up rich foods such as eggs, milk, butter and sugar which were traditionally forbidden during the 40 days of Lent.
Today, this custom has focused more on refraining from alcohol, cigarettes, sweets and chocolate.
Pancake Tuesday is also known as Mardi Gras (which translates from French as “Fat Tuesday”), Carnival (Latin meaning “farewell to the flesh”) and Fasnacht (German for “night of the fast”).
So, as you’re tucking into your pancakes this Tuesday, you may be feeling slightly guilty as your beloved canine is looking up at you with those puppy dog eyes! But the good news is that there is a pancake recipe suitable for your dog.
