Rockster – Duck A La Royale

Rockster: Duck A La Royale review

83.6/100Outstanding
WetPuppyAdult

Rockster reads more like a butcher's order than a recipe, and the eight recipes split evenly between our Excellent and Outstanding bands. Cuts are itemised down to lung and tongue, and the strongest labels print a percentage beside each one. Behind the meat sits a small garden of quinoa, pumpkin, berries and roots.

Our view

Likely to suit

  • An unusual animal: rabbit, venison and duck each head a recipe
  • Organs itemised, with muscle, lung, liver and tongue printed by weight on several labels
  • Households buying organic, declared on every label
  • Small dogs and light eaters, with a 195 g can alongside the 340 g and 400 g sizes
  • A small plant side, kept to low single figures on most labels
  • Joint support in the venison recipe, with green lipped mussels at 1%

Worth watching

  • Both Fisherman's Dream recipes add calamari and mussels to the salmon
  • Salmon oil in the beef, duck and venison recipes, so those three are not fish free
  • The two Boeuf Du Cap sizes share a list but print very different analysis panels
  • Chickenrella and Duck A La Royale leave ash off the analysis

The top scorer in the range, and one of only two listed beyond adulthood.

Eight recipes across salmon, beef, chicken, duck, rabbit and venison, with organic ingredients declared on every label. Where percentages are printed, the named animal runs from 82% to 86%, and organs are itemised by name and weight: liver, lung, tongue, heart and gizzard.

The plant side is small and chosen, with quinoa doing most of the work on the recipes that carry it, and fibre runs high as a result. Vitamins and minerals are folded into the ingredient list on some labels and printed as a separate panel on others, so the doses do not compare line for line.
